The Philippines is the main producing area of lateritic nickel ore. This type of nickel ore has a complex composition which can be roughly divided into two types: limonite and silicon-magnesium nickel. It is accompanied by only a small amount of cobalt but without sulfur and calorific value, and easy to mine in the open pit.

Generally, like other ore beneficiaiton plants, laterite nickel ore processing needs several stages includes ore washing, crushing and screening, milling by ball mill, magnetic and froth flotation separating and drying and melting. The distribution of useful mineral nickel varies with the nature of the ore. Most useful minerals are rich in fine-grained grades, and you can learn that from Philippines BNML limonite with +50mm whose nickel grade is as high as 2.89%.

laterite nickel ore mostly exists in sapropelic deposits, and the content of laterite nickel increases with depth. The raw nickel ore is always companied by clay and impurities. The washing ore process can remove clay and impurities before crushing and beneficiation operations, which improves operating efficiency and helps to obtain high-grade nickel concentrate.

The ore washing equipment used in laterite ore mainly is a coarse and fine material screw washer. It can help you realize wash, classify and dewater lateritic nickel ore with -10mm or 3/8" in one time. Compared with other ore washing machines, screw washers can retain more fine-sized products because of the unique design of sand recovery units, which greatly increases washing efficiency.

The crushing process is necessary because when raw laterite nickel ore is excavated, it is often accompanied by columnar rocks with incomplete weathering and with large size. After crushing, the huge block of nickel ore would be reduced to a small size, which ideally avoids screen mesh blocking.

A Cone crusher is the best machine to crush nickel ore. The lamination crushing principle makes the particle shape of the product even and excellent. In the process, a primary cone crusher can reduce the material size to -5 inches, and then a short head cone crusher makes a further reduction to -1/2" in size. Various types of crushing chamber perform high adaptability. And the most outstanding feature is that its large head displacement allows a greater volume of material flow at every circle.

Ball mill is used for wet or dry grinding ores and other raw materials, it can give a controlled final grind and produce flotation feed of a uniform size. It is operated in a closed circuit with a particle-size measurement device and size-control cyclones which can send correct-size material onto flotation.

Wet magnetic separation is applied to get separated pyrrhotite. After that process, the pyrrhotite with -100 does not meet the requirements of froth flotation, which means that it should be reduced to -200 mesh in a ball mill, and the classification can be accomplished with screens and cyclones.

The next step is to send -200 mesh pyrrhotite to froth flotation equipment which can produce 3% nickel concentrate. But that is not the end, the left nonmagnetic ore should be sent to a series of rougher, cleaner flotation cells, and from that, you can get around 31% copper concentrate. And the end, the tailings can be also used to recover the nickel by being sent to another flotation cell, thus the concentrate is combined with the 3% nickel concentrate to produce a 12% nickel concentrate.

Drying by rotary dryer and rotary kiln. Philippines nickel ore contains a large amount of moisture, drying process is important and necessary. A rotary dryeris typically used to remove free moisture from the crushed nickel ore, and once nickel ore has been dried, it is processed in a rotary kiln to remove chemically bound moisture and the oxide component of the ore. That process is called pre-reduction. In order to avoid the formation of olivine above 800C, the final plan is to control it at 770C in the rotary kiln.

Reduction Smelting After processed by the rotary kiln, nickel is further reduced and smelted in an electric furnace. If you want to increase the grade of crude nickel-iron in the electric furnace to 35%, you can adopt the technology which cancels the blending of limestone flux. But you must focus on characteristics of laterite ore, the physicochemical reaction in the furnace, and other economic indicators.

When finishing the smelting step, the material would be fed into the rotary cooler at the end of the cylinder and cooled directly. By showering the material through a cool air stream, or by spraying water onto the external surface of the cylinder, the final nickel product is then discharged at the other end.

Because nickel is corrosion, oxidation, high-temperature resistant, and has high strength and good ductility, it has a wide range of applications, especially in stainless steel and heat-resistant steel. In the current consumption of nickel, the iron and steel and non-ferrous metal smelting industries account for about 65% to 70% of the total nickel consumption.

Our small-scale miners Ball Mills use horizontal rotating cylinders that contain the grinding media and the particles to be broken. The mass moves up the wall of the cylinder as it rotates and falls back into the toe of the mill when the force of gravity exceeds friction and centrifugal forces. Particles are broken in the toe of the mill when caught in the collisions between the grinding media themselves and the grinding media and the mill wall. In ball mills, the grinding media and particles acquire potential energy that becomes kinetic energy as the mass falls from the rotating shell. Ball mills are customarily divided into categories that are mainly defined by the size of the feed particles and the type of grinding media.

Intermediate and fine size reduction by grinding is frequently achieved in a ball mill in which the length of the cylindrical shell is usually 1 to 1.5 times the shell diameter. Ball mills of greater length are termed tube mills, and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as pebble mills. In general, ball mills can be operated either wet or dry and are capable of producing products on the order of 100 um. This duty represents reduction ratios as great as 100.

The ball mill, an intermediate and fine-grinding device, is a tumbling drum with a 40% to 50% filling of balls. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture. Very large tonnages can be ground with these devices because they are very effective material handling devices. The feed can be dry, with less than 3% moisture to minimize ball coating, or a slurry can be used containing 20% to 40% water by weight. Ball mills are employed in either primary or secondary grinding applications. In primary applications, they receive their feed from crushers, and in secondary applications, they receive their feed from rod mills, autogenous mills, or semi-autogenous mills. Regrind mills in mineral processing operations are usually ball mills, because the feed for these applications is typically quite fine. Ball mills are sometimes used in single-stage grinding, receiving crusher product. The circuits of these mills are often closed with classifiers at high-circulating loads.

All ball mills operate on the same principles. One of these principles is that the total weight of the charge in the mill-the sum of the weight of the grinding media, the weight of the material to be ground, and any water in the millis a function of the percentage of the volume of the mill it occupies.

The power the mill draws is a function of the weight of the charge in the mill, the %of volumetric loading of the mill, the %of critical speed, which is the speed in RPM at which the outer layer of the charge in the mill will centrifuge.

For closed grinding circuits producing typical ball mill products, indirect and direct on-line measurements of the product size are available. The indirect means are those which assume that the product size is relatively constant when the feed condition to the classifying unit and the operating conditions in the classifying unit are constant. One example is maintaining a constant mass flow, pulp density and pressure in the feed to the cyclone classifier.

By using math modeling, it is possible to calculate the product size from measured cyclone classifier feed conditions and circuit operating data, thus establishing the effect on the particle size distribution in the product for changes in the variables.

Direct on-line means to measure either particle size or surface area are available for typical ball mill circuit products. These require the means to obtain representative or at least consistent samples from the grinding circuit product stream. These direct means and the calculated product particle size distributions can be used to:

Small variations in the feed size to ball mill circuits generally is not critical to the calculation of operating work index because they make a very small change in the 10F factor. Thus, a computer program can be developed to calculate operating work indices from on-line data with the feed size a constant and with the program designed to permit manually changing this value, as required to take into account changes in feed size resulting from such things as drawing down feed bins, crusher maintenance, work screen surfaces in the crushing plant, etc. which are generally known in advance, or can be established quickly. Developments underway for on-line measurement of particle size in coarser material which when completed will permit measuring the feed size used to calculate operating work indices.

recorded by a data logger, gives continuous means to report comminution circuit performance and evaluate in-plant testing. Changes in Wio indicated on data loggers alert operating and supervisory personnel that a change has occurred in either the ore or in circuit performance. If sufficient instrumentation is available, the cause for a problem can often be located from other recorded or logged data covering circuit and equipment operation, however, generally the problem calls for operator attention to be corrected.

Wio can be used to determine the efficiency of power utilization for the entire comminution section of a mill, and for the individual circuits making up the comminution section. The efficiency of a comminution circuit is determined by the following equation.

Wi is obtained by running the appropriate laboratory tests on a composite sample of circuit feed. Wio is calculated from plant operating data covering the period when the feed sample was taken. Since Wi from laboratory tests refers to specific conditions for accurate efficiency determinations, it is necessary to apply correction factors as discussed in The Tools of Power Power to Wio to put the laboratory and operating data on the same basis.

To-date, there is no known way to obtain standard work index data from on-line tests. Continuous measurement of comminution circuit efficiency is not possible and thus efficiency is not available for circuit control. Using laboratory data and operating data, efficiency can be determined for overall section and individual circuit for evaluation and reporting. Just monitoring Wio and correcting operating problems as they occur will improve the utilization of the power delivered to the comminution circuits.

Samples taken from the chips around blast hole drillings and from broken ore in the pit or mine for laboratory work index and other ore characteristic determinations before the ore is delivered to the mill, can be used to predict in advance comminution circuit performance. Test results can also be used for ore blending to obtain a more uniform feed, particularly to primary autogenous and semi-autogenous circuits.

We sell Small Ball Mills from 2 to 6 (600 mm X 1800 mm) in diameter and as long as 10 (3000 mm) in length. The mills are manufactured using a flanged mild steel shell, cast heads, overflow discharge, removable man door, spur type ring gear, pinion gear assembly with spherical roller bearings, replaceable roller bronze trunnion bearings, oil lubrication, replaceable trunnion liners with internal spirals, rubber liners and lifters, feed spout with wash port, discharge trommel with internal spiral, motor and gear reducer drive, direct coupled to pinion gear, gear guard and modular steel support frame. All ball mills always come withOSHA-type gear guard.

A PULP level sufficiently high to interpose a bed of pulp, partly to cushion the impact of the balls, permits a maximum crushing effect with a minimum wear of steel. The pulp level of theseSmall Ball Millscan be varied from discharging at the periphery to discharging at a point about halfway between the trunnion and the periphery.The mill shell is of welded plate steel with integral end flanges turned for perfect alignment, and the heads are semi-steel, with hand holes in the discharge end through which the diaphragm regulation is arranged with plugs.The trunnion bearings are babbitted, spherical, cast iron, and of ample size to insure low bearing pressure; while the shell and saddle are machined to gauge so that the shells are interchangeable.

Data based on:Wet grinding, single stage, closed circuit operation: feed:( one way dimension); Class III ore. All mills:free discharge, grated type, rapid pulp flow. N. B.for overflow type mills: capacity 80%power 83%. Dimensions :diameters inside shell without linerslengths working length shell between end liners.

The CIW is a Small Ball Mill thats belt driven, rigid bearing, wet grinding, trunnion or grate discharge type mill with friction clutch pulley and welded steel shell. The 7 and 8 foot diameter mills are of flange ring construction with cut gears while all other sizes have cast tooth gears. All these mills are standard with white iron bar wave type shell liners except the 8 foot diameter mill which is equipped with manganese steel liners. The horsepowers shown in the table are under running conditions so that high torque or wound rotor (slip ring) motors must be used. Manganese or alloy steel shell or head liners and grates can be supplied with all sizes of mills if required. Alloy steel shell liners are recommended where 4 or larger balls are used and particularly for the larger sized mills.

Small (Muleback Type) Ball Mill is built for muleback transportation in 30 and 3 diameters (inside liners). A 4 (Muleback Type) Ball Mill is of special design and will be carefully considered upon request. Mankinds search for valuable minerals often leads him far away from modern transportation facilities. The potential sources of gold, silver and strategic minerals are often found by the prospector, not close by our modern highways, but far back in the mountains and deserts all over the world. The Equipment Company has realized this fact, and therefore has designed a Ball Mill that can be transported to these faraway and relatively inaccessible properties, either by the age old muleback transportation system, or by the modern airplane. As a result these properties may now obtain a well-designed ball mill with the heaviest individual piece weighing only 350 pounds.

The prime factor considered in this design was to furnish equipment having a maximum strength with a minimum weight. For this reason, these mills are made of steel, giving a high tensile strength and light weight to the mills. The muleback design consists of the sturdy cast iron head construction on the 30 size and cast steel head construction on the larger sizes. The flanges on the heads are arranged to bolt to the rolled steel shell provided with flanged rings. When required, the total length of the shell may consist of several shell lengths flanged together to provide the desired mill length. Liners, bearings, gears and drives are similar to those standard on all Ball Mills.

This (Convertible) and Small Ball Mill is unique in design and is particularly adapted to small milling plants. The shell is cast in one piece with a flange for bolting to the head. In converting the mill from a 30x 18 to a 30x 36 unit with double the capacity, it is only necessary to secure a second cast shell (a duplicate of the first) and bolt it to the original section.

30 Convertible Ball Mills are furnished with scoop feeders with replaceable lips. Standard mills are furnished with liners to avoid replacement of the shell; however, themill can be obtained less liners. This ball mill is oftendriven by belts placed around the center, although gear drive units with cast gears can be furnished. A Spiral Screen can be attached to the discharge.

This mill may be used for batch or intermittent grinding, or mixing of dry or wet materials in the ore dressing industry, metallurgical, chemical, ceramic, or paint industries. The material is ground and mixed in one operation by rotating it together with balls, or pebbles in a hermetically sealed cylinder.

The cast iron shell which is bolted to the heads is made with an extra thick wall to give long wearing life. Two grate cleanout doors are provided on opposite sides of the shell by means of which the mill can be either gradually discharged and washed, while running, or easily and rapidly emptied and flushedout while shut down. Wash-water is introduced into the interior of the mill through a tapped opening in the trunnion. The mill may be lined with rubber, silex (buhrstone) or wood if desired.

The Hardinge Conical Ball Mill has been widely used with outstanding success in grinding many materials in a wide variety of fields. The conical mill operates on the principle of an ordinary ball mill with a certain amount of classification within the mill itself, due to its shape.

Sizes of conical mills are given in diameter of the cylindrical section in feet and the length of the cylindrical section in inches. Liners can be had of hard iron, manganese steel or Belgian Silex. Forged steel balls or Danish Flint Pebbles are used for the grinding media, depending upon the material being milled.

The Steel Head Ball-Rod Mill gives the ore dressing engineer a wide choice in grinding design so that he can easily secure a Ball-Rod Mill suited to his particular problem. The successful operation of any grinding unit is largely dependent on the method of removing the ground pulp. The Ball-Rod Mill is available with five types of discharge trunnions, each type obtainable in small, medium or large diameters. The types of discharge trunnions are:

The superiority of the Steel Head Ball-Rod Mill is due to the all steel construction. The trunnions are an integral part of the cast steel heads and are machined with the axis of the mill. The mill heads are assured against breakage due to the high tensile strength of cast steel as compared to that of the cast iron head found on the ordinary ball mill. Trunnion Bearings are made of high- grade nickel babbitt.

Steel Head Ball-Rod Mills can be converted intolarger capacity mills by bolting an additional shell lengthonto the flange of the original shell. This is possible because all Steel Head Ball or Rod Mills have bearings suitable for mills with length twice the diameter.

Head and shell liners for Steel Head Ball-Rod Mills are available in Decolloy (a chrome-nickel alloy), hard iron, electric steel, molychrome steel, and manganese steel. Drive gears are furnished either in cast tooth spur gear and pinion or cut tooth spur gear and pinion. The gears are furnished as standard on the discharge end of the mill, out of the way of the classifier return feed, but can be furnished at the mill feed end by request. Drives may be obtained according to the customers specifications.

If this is true, there is significance in the factthat international Nicked and Climax Molybdenum, theworlds largest producers of two important steel alloys, areboth users of MARCY Mills exclusively. With international interest centered on increasingproduction of gold, it is even more significant that MARCYMills are the predominant choice of operators in everyimportants gold mining camp in the world.

Ball Mill. Intermediate and fine size reduction by grinding is frequently achieved in a ball mill in which the length of the cylindrical shell is usually 1 to 1.5 times the shell diameter. Ball mills of greater length are termed tube mills, and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as pebble mills. In general, ball mills can be operated either wet or dry and are capable of producing products on the order of 100 pm. This duty represents reduction ratios as great as 100.

The ball mill, an intermediate and fine-grinding device, is a tumbling drum with a 40% to 50% filling of balls (usually steel or steel alloys). The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture. Very large tonnages can be ground with these devices because they are very effective material handling devices. The feed can be dry, with less than 3% moisture to minimize ball coating, or a slurry can be used containing 20% to 40% water by weight. Ball mills are employed in either primary or secondary grinding applications. In primary applications, they receive their feed from crushers, and in secondary applications, they receive their feed from rod mills, autogenous mills, or semiautogenous mills. Regrind mills in mineral processing operations are usually ball mills, because the feed for these applications is typically quite fine. Ball mills are sometimes used in single-stage grinding, receiving crusher product. The circuits of these mills are often closed with classifiers at high-circulating loads.

These loads maximize throughput at a desired product size. The characteristics of ball mills are summarized in the Table, which lists typical feed and product sizes. The size of the mill required to achieve a given task-that is, the diameter (D) inside the liners-can be calculated from the design relationships given. The design parameters must be specified.

The liner- and ball-wear equations are typically written in terms of an abrasion index (Bond 1963). The calculated liner and ball wear is expressed in kilograms per kilowatt-hour (kg/kWh), and when multiplied by the specific power (kWh/t), the wear rates are given in kilograms per ton of feed. The wear in dry ball mills is approximately one-tenth of that in wet ball mills because of the inhibition of corrosion. The efficiency of ball mills as measured relative to single-particle slow-compression loading is about 5%. Abrasion indices for five materials are also listed in the Table.

The L/D ratios of ball mills range from slightly less than 1:1 to something greater than 2:1. The tube and compartment ball mills commonly used in the cement industry have L/D ratios 2.75:1 or more. The fraction of critical speed that the mill turns depends on the application, and most mills operate at around 75% of critical speed. Increased speed generally means increased power, but as the simulations presented in Figure 3.26 show, it can also produce more wasted ball impacts on the liners above the toe. causing more wear and less breakage.

There are three principal forms of discharge mechanism. In the overflow ball mill, the ground product overflows through the discharge end trunnion. A diaphragm ball mill has a grate at thedischarge end. The product flows through the slots in the grate. Pulp lifters may be used to discharge the product through the trunnion, or peripheral ports may be used to discharge the product.

The majority of grinding balls are forged carbon or alloy steels. Generally, they are spherical, but other shapes have been used. The choice of the top (or recharge) ball size can be made using empirical equations developed by Bond or Azzaroni or by using special batch-grinding tests interpreted in the content of population balance models. The effect of changes in ball size on specific selection functions has been found to be different for different materials. A ball size-correction method can be used along with the specific selection function scale-up method to determine the best ball size. To do this, a set of ball size tests are performed in a batch mill from which the specific selection function dependence on ball size can be determined. Then, the mill capacities used to produce desired product size can be predicted by simulation using the kinetic parameter corresponding to the different ball sizes.

The mill liners used are constructed from cast alloy steels, wear-resistant cast irons, or polymer (rubber) and polymer metal combinations. The mill liner shapes often recommended in new mills are double-wave liners when balls less than 2.5 in. are used and single-wave liners when larger balls are used. Replaceable metal lifter bars are sometimes used. End liners are usually ribbed or employ replaceable lifters.

The typical mill-motor coupling is a pinion and gear. On larger mills two motors may be used, and in that arrangement two pinions drive one gear on the mill. Synchronous motors are well suited to the ball mill, because the power draw is almost constant. Induction, squirrel cage, and slip ring motors are also used. A high-speed motor running 600 to 1,000 rpm requires a speed reducer between the motor and pinion shaft. The gearless drive has been installed at a number of locations around the world.

extraction of nickel | nickel ore mining | mining equipment for sale

The laterite nickel ore is complex in composition and can be roughly divided into two types: limonite type and silicon magnesium-nickel type. The main elements are nickel, cobalt and manganese. The laterite mining method generally uses open-pit mining. The ore body generally does not require rock drilling or blasting. Nickel ore processing plant can directly use the excavator to shovel the ore. The thinner ore layers are first collected by the bulldozer and then shovel. nickel mining is divide into copper-nickel mining and extraction of nickel from sulphide ore. Below the cover of the Ramu laterite nickel deposit in Papua New Guinea, there are yellow limonite deposits, residual layers, gravel-bearing residual rocks and pure peridotite bedrock; under the Philippines mining Nonoc laterite ore cover are limonite Layer, transition layer, residual ore layer and bedrock; Cameroon red earth cobalt-nickel ore is red soil layer, breccia, iron-aluminum and serpentine bedrock. In general, the laterite ore mainly contains a gravel layer, and is often accompanied by columnar rock phenomenon with incomplete weathering. Because columnar rocks often have high-grade ore and the blockiness and hardness are relatively large, from the perspective of mineral processing. It is said that it is necessary to use crushing equipment to extract nickel from its ore.

The extraction of nickel process generally consists of crushing, sieving, washing, re-selection, grinding, and slurry concentration, or the nickel leaching method. The target element nickel distribution varies with the nature of the ore, mostly contained in fine-grained grades. For example, the nickel minerals of the Ramu laterite mine in Papua New Guinea are mainly enriched in fine mud of -53 m. There are uncommon, such as Cameroon cobalt nickel manganese laterite ore, the nickel are mainly concentrated in +0. In the grain size above 3mm, the Philippine BNML nickel ore limonite + ore nickel grade above 50mm 2. 89%, the coarser the grade of ore, the higher the grade of nickel.

Laterite nickel ore is often accompanied by a columnar rock with incomplete weathering. The block size may exceed 1m. If you dont crush them, only use the original ore bin to control the ore size. The rock is easily stuck in the sieve hole, affects the normal supply during the nickel extraction process. Therefore, it is recommended that the laterite mine should be crushed better before washing. Conventional stone crushers such as rotary crusher, jaw crusher, impact crusher, hammer crusher, cone crusher and roller crushers, all have a common disadvantage that they cannot effectively handle materials with high mud content, high water content and high viscosity. The double roller crusher can effectively overcome the shortcomings of conventional crusher. the working principle of double roller crusher is that the shearing force acts directly on the ore material through the high-torque, low-speed transmission system, so that the force is along the weak and fragile parts of the material. Produces a huge crushing force to break it, forming a unique crushing particle size control technology. When the crusher is working, the material can be discharged into the upper part of the whole machine. The size of the feed port is larger than that of any crusher, and it is not easy to cause the blockage. The discharge port is also very large, and almost the entire lower part of the equipment can be discharged. product. The movement of the double-toothed tooth causes the material to be broken and can be forcibly discharged, so it is especially suitable for viscous materials and materials with high water content, and the discharge opening is not blocked. The double-roller screening crusher production plant mainly in British MMD company and Sandvik company.

The washing equipment used in the nickel mining process mainly includes a gold trommel scrubber, a spiral washing machine and a stirring scrubbing tank. The Nonoc laterite nickel mine washing system is composed of a cylindrical gold trommel washing machine and two spiral washing machines. The Australian laterite nickel ore is washed by a trommel scrubber. The specifications of the trommel scrubber are: 5m 11. 9m for limonite, 4m 7. 4m is used for residual ore. The grit of the first-stage hydrocyclone of laterite mine is fed into the mixing scrubbing tank and then graded into the second-stage hydrocyclone. The Papua New Guinea laterite nickel mine adopts a combined washing method of a cylinder washing machine and a spiral washer machine. The gold trommel washing machine has a specification of 3m 10m, and the tank type washing machine has a specification of LW36 35. Generally speaking, after a section of crushing, the cylinder size of the cylinder is used to feed the ore 300mm; the size of the log washing machine is 50mm. For most of the laterite nickel ore, the nickel-cobalt is mainly rich in In the 3mm grain class, the grain size above +3mm is discarded as waste rock. For example, 3mm ~ 50mm of laterite mine is recycled by sanding of the log washing machine, and the material of +50mm is thrown through the cylinder of the cylinder washing machine. Waste. But there are also uncommon such as Cameroon cobalt nickel manganese laterite ore, its useful mineral cobalt nickel is mainly rich in + 0. 3mm or more, 0. In the 3mm range, the slime is mainly thrown away as tailings. For this ore type laterite nickel ore, the use of cylindrical washing machine and trough washing machine cannot effectively remove 0. 3mm fine-grain grade slime, this red earth mine washing operation itself does not produce tailings, its purpose is mainly to scrub the ore and the slime, fully stir and de-sludge through a cyclone or hydraulic classification equipment. However, the washing and washing equipment may consider the use of the stirring scrubbing tank, but the washing condition of the stirring scrubbing tank and the energy consumption of the stirring should be fully considered according to the stirring scrubbing test. Extraction of nickel research has a very positive effect on the nickel mining process, extraction of manganese, extraction tin and other mining minerals. Nickel laterite processing is always upgrading.
