Iron ore beneficiation begins with the milling of extracted ore in preparation for further operations to recoveriron values. Milling operations are designed to produce uniform size particles by crushing, grinding,and wet or dry classification. The capital investment and operation costs of milling equipment are high.

Crushing is a multistage process and may use dry iron ore feed. Typically, primary crushing andscreening take place at the mine site. Primary crushing is accomplished by using jaw crusher or gyratorycrushers. Primary crushing yields chunks of ore ranging in size from 6 to 10 inches. Oversize material is passed through additional secondary crushers and classifiers to achieve the desired particlesize.

In iron ore beneficiation operation, the raw iron ore materials will be first reduced to small particle size. It may require crushing the material tomaximize the production of minus 2mm. According to SBMs experience in crushing technology, we recommended the installation of acone crusher to reduce the minus 100mm pebblesand a VSI crusher machine to fine crush the cone crusherproduct.

The iron ore crushers with low price are also used in the industrial minerals, mining, recycling and general quarrying industries. A widerange of materials are processed through SBM iron crushers worldwide. SBM experts can customize crushing solution in iron ore beneficiation according to your requirements. Here are some popular iron ore crusher machine types. Please contact us for more information.

According to different final products applications, varioustypes of crusher equipment are required, such as jaw crusher for primary crushing, impact crusher and hammer crusher for secondary crushing, cone crusher for secondary and tertiary crushing. Iron ore crusher prices are different according to crusher types and production capacities.

The VSI crusher for iron ore beneficiation uses a unique rock-on-rockcrushing action whereby the feed materialgrinds and impacts against itself, minimizingwear costs and maintenance down-time. Thisis especially important in applications such asiron ore processing where the feed material istypically hard and abrasive and wear costs arepotentially very high.

Jaw Crusher Jaw crusher is available with stationary, mobile and portable applications. The jaw crushers combine a high reduction ratio and increased capacity with any feed materials: from extra hard rock to recycled materials. This is achieved through several unique features such as higher crushing speed, optimized kinematics, a longer stroke and easy adjustment.

Impact Crusher Impact crushers are based upon several decades of experience with the impact method. We offer a complete range of impact crushers for stationary, semi-mobile fully mobile applications in both primary and secondary crushing.

Cone Crusher Cone crusher is a stationary crusher. These crushers are hydraulic pressure crushers designed to crush a high ratio for high productivity. Cone crushers are ideal for secondary and fine crushing.

mineral processing operating cost estimate of ore treatment

Only where a group of mines operates in a single district are costs comparable and then only with reservations. In general, cost systems are fairly uniform, yet in studying costs of a number of plants it is noticeable that in some cases there is a tendency to omit certain operations which are proper charges against ore dressing and treatment. These should cover the first stage of coarse crushing, whether it be underground or on the surface, as well as the disposal of the residue, the recovery of bullion, and returns from products sold and must include the cost for labor, power, supplies, repairs, and compensation.

In 1936 when data were being compiled for Cyanidation and Concentration of Gold and Silver Ores, considerable published information was available on milling costs in various parts of the world. At the present time, however, it is extremely difficult to obtain reliable figures on the cost of ore treatment owing to the fact that during a period of rising prices and wages the mine managements do not consider current cost data typical of normal operation and are unwilling to release them for publication.

Another factor which applies particularly to the United States and Canada and which tends to make cost-per-ton figures unreliable is the disparity between the rated capacity of many of the mills and the actualtonnage being handled today. This is partly attributed to shortage ofunderground labor and partly to the fact that during the war period not only was maintenance heavier than normal but opportunities for improvements in technique were lacking.

Figure 97 shows the relationship between the tonnage capacity and total milling cost, per ton based on the 1939 figures for a number of typical Canadian plants. Saving in overhead and labor is the principal factor that enters into the decreasing cost per ton for the larger operations.

Considerable variation will be found in individual cases depending upon hardness of ore, fineness of grind, hours of treatment required, reagent consumption, and the situation of the property in its bearing on cost of supplies, etc.

The total cost of producing an ounce of gold in Canada increased from $22.35 in 1939 to $32.07 in 1945, according to the report of the director of the Ontario Mining Association for 1945. This represents a 43.5 per cent increase. From various other data which are available, however, it appears that milling and treatment costs (mining excluded) have probably not risen on the average over about 30 per cent. The broken line in Fig. 97 indicates estimated present (1948) average cost on the basis of this 30 per cent rise.

Kerr Addison, for instance, is milling 2800 tons per day for a total of 72 cents per ton. Hollinger in the 40 weeks ending Oct. 6, 1948, milled an average of 3627 tons per day at a total cost of 77.29 cents per ton, of which 37.90 cents was labor cost.

Where a combination of flotation and cyanidation is used, the combined cost approximates this same percentage. This includes such items as heating and lighting, sampling, assaying, experimental work, repairs, and various indirect costs, depending upon the system of cost distributions in use. It is partly because widely different methods of charging out such costs have been adopted that considerable divergence in overall cost distribution is to be found.

Consolidated Beattie gold mines is a good example of a large plant employing flotation, roasting, and the cyanidation of concentrates. Approximately 1300 tons per day of arsenical gold is treated for an overall cost of $1.05 per ton, distributed as shown in Table 98.

The roasting cost works out at approximately $1.22 per ton of concentrate, distributed as shown in Table 99. At MacLeod Cockshutt Gold Mines, Ltd., the cost of roasting in 1941- 1942 was 32 cents per ton milled or $1.25 per ton of ore roasted, while at Lake Shore mines for the same year the cost was about 80 cents per ton roasted.

The 700-ton mill operated by the Standard Cyanide Co. in Nevada between the years 1939 and 1942, when it was closed as a result of government order during the Second World War, succeeded in making a profit from ore carrying as little as 0.06 oz. gold per ton. Cheap, open-pit mining methods were used, and good extractions were obtained when grinding to only 3 mesh. These, among other factors, made for extremely low-cost operation. The 596,482 tons milled yielded $1.86 per ton at a total cost of $1.18 per ton of which $0.52 was milling cost.

The power required in cyanide plants varies with type of ore, fineness of grind, etc., but in general the range is 20 to 30 kw.-hr. per ton of daily capacity. The power distribution at Preston East Dome mines in Ontario, Canada, is shown in Table 102. The relative distribution of power between the crushing and grindingsections will vary according to the fineness of crushing and the type of plant, but on the average these departments will together consume 60 to 70 per cent of the total power.

Flotation. The power consumption for straight single-product flotation plants varies, according to A. M. Gaudin, from 12 to 20 kw.-hr. perton, depending on the fineness to which the ore is ground. The average percentage power costs for the various.departments of seven United States producers is given in Table 103.

The power consumption at Randfontein Estates, which is milling 13,000 tons per day by the older sand-slime process, is shown in Table 104. Distribution figures for the new 2100-ton-per-day Marievale plant are shown in Table 105.

After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore. The beneficiation process should be as efficient and simple as possible, such as the development of energy-saving equipment, and the best possible results with the most suitable process. In the iron ore beneficiation factory, the equipment investment, production cost, power consumption and steel consumption of crushing and grinding operations often account for the largest proportion. Therefore, the calculation and selection of crushing and grinding equipment and the quality of operation management are to a large extent determine the economic benefits of the beneficiation factory.

There are many types of iron ore, but mainly magnetite (Fe3O4) and hematite (Fe2O3) are used for iron production because magnetite and hematite have higher content of iron and easy to be upgraded to high grade for steel factories.

Due to the deformation of the geological properties, there would be some changes of the characteristics of the raw ore and sometimes magnetite, hematite, limonite as well as other types iron ore and veins are in symbiosis form. So mineralogy study on the forms, characteristics as well as liberation size are necessary before getting into the study of beneficiation technology.

1. Magnetite ore stage grinding-magnetic separation process The stage grinding-magnetic separation process mainly utilizes the characteristics of magnetite that can be enriched under coarse grinding conditions, and at the same time, it can discharge the characteristics of single gangue, reducing the amount of grinding in the next stage. In the process of continuous development and improvement, the process adopts high-efficiency magnetic separation equipment to achieve energy saving and consumption reduction. At present, almost all magnetic separation plants in China use a large-diameter (medium 1 050 mm, medium 1 200 mm, medium 1 500 mm, etc.) permanent magnet magnetic separator to carry out the stage tailing removing process after one stage grinding. The characteristic of permanent magnet large-diameter magnetic separator is that it can effectively separate 3~0mm or 6~0mm, or even 10-0mm coarse-grained magnetite ore, and the yield of removed tails is generally 30.00%~50.00%. The grade is below 8.00%, which creates good conditions for the magnetic separation plant to save energy and increase production.

2.Magnetic separation-fine screen process Gangue conjoined bodies such as magnetite and quartz can be enriched when the particle size and magnetic properties reach a certain range. However, it is easy to form a coarse concatenated mixture in the iron concentrate, which reduces the grade of the iron concentrate. This kind of concentrate is sieved by a fine sieve with corresponding sieve holes, and high-quality iron concentrate can be obtained under the sieve.

There are two methods for gravity separation of hematite. One is coarse-grained gravity separation. The geological grade of the ore deposit is relatively high (about 50%), but the ore body is thinner or has more interlayers. The waste rock is mixed in during mining to dilute the ore. For this kind of ore, only crushing and no-grinding can be used so coarse-grained tailings are discarded through re-election to recover the geological grade.

The other one is fine-grain gravity separation, which mostly deals with the hematite with finer grain size and high magnetic content. After crushing, the ore is ground to separate the mineral monomers, and the fine-grained high-grade concentrate is obtained by gravity separation. However, since most of the weak magnetic iron ore concentrates with strong magnetic separation are not high in grade, and the unit processing capacity of the gravity separation process is relatively low, the combined process of strong magnetic separation and gravity separation is often used, that is, the strong magnetic separation process is used to discard a large amount of unqualified tailings, and then use the gravity separation process to further process the strong magnetic concentrate to improve the concentrate grade.

Due to the complexity, large-scale mixed iron ore and hematite ore adopt stage grinding or continuous grinding, coarse subdivision separation, gravity separation-weak magnetic separation-high gradient magnetic separation-anion reverse flotation process. The characteristics of such process are as follows:

(1) Coarse subdivision separation: For the coarse part, use gravity separation to take out most of the coarse-grained iron concentrate after a stage of grinding. The SLon type high gradient medium magnetic machine removes part of the tailings; the fine part uses the SLon type high gradient strong magnetic separator to further remove the tailings and mud to create good operating conditions for reverse flotation. Due to the superior performance of the SLon-type high-gradient magnetic separator, a higher recovery rate in the whole process is ensured, and the reverse flotation guarantees a higher fine-grained concentrate grade.

(2) A reasonable process for narrow-level selection is realized. In the process of mineral separation, the degree of separation of minerals is not only related to the characteristics of the mineral itself, but also to the specific surface area of the mineral particles. This effect is more prominent in the flotation process. Because in the flotation process, the minimum value of the force between the flotation agent and the mineral and the agent and the bubble is related to the specific surface area of the mineral, and the ratio of the agent to the mineral action area. This makes the factors double affecting the floatability of minerals easily causing minerals with a large specific surface area and relatively difficult to float and minerals with a small specific surface area and relatively easy to float have relatively consistent floatability, and sometimes the former has even better floatability. The realization of the narrow-level beneficiation process can prevent the occurrence of the above-mentioned phenomenon that easily leads to the chaos of the flotation process to a large extent, and improve the beneficiation efficiency.

(3) The combined application of high-gradient strong magnetic separation and anion reverse flotation process achieves the best combination of processes. At present, the weak magnetic iron ore beneficiation plants in China all adopt high-gradient strong magnetic separation-anion reverse flotation process in their technological process. This combination is particularly effective in the beneficiation of weak magnetic iron ore. For high-gradient strong magnetic separation, the effect of improving the grade of concentrate is not obvious. However, it is very effective to rely on high-gradient and strong magnetic separation to provide ideal raw materials for reverse flotation. At the same time, anion reverse flotation is affected by its own process characteristics and is particularly effective for the separation of fine-grained and relatively high-grade materials. The advantages of high-gradient strong magnetic separation and anion reverse flotation technology complement each other, and realize the delicate combination of the beneficiation process.

The key technology innovation of the integrated dry grinding and magnetic separation system is to "replace ball mill grinding with HPGR grinding", and the target is to reduce the cost of ball mill grinding and wet magnetic separation.

HPGRs orhigh-pressure grinding rollshave made broad advances into mining industries. The technology is now widely viewed as a primary milling alternative, and there are several large installations commissioned in recent years. After these developments, anHPGRsbased circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

The wear on a rolls surface is a function of the ores abrasivity. Increasing roll speed or pressure increases wear with a given material. Studs allowing the formation of an autogenous wear layer, edge blocks, and cheek plates. Development in these areas continues, with examples including profiling of stud hardness to minimize the bathtub effect (wear of the center of the rolls more rapidly than the outer areas), low-profile edge blocks for installation on worn tires, and improvements in both design and wear materials for cheek plates.

With Strip Surface, HPGRs improve observed downstream comminution efficiency. This is attributable to both increased fines generation, but also due to what appears to be weakening of the ore which many researchers attribute to micro-cracking.

As we tested , the average yield of 3mm-0 and 0.15mm-0 size fraction with Strip Surface was 78.3% and 46.2%, comparatively, the average yield of 3mm-0 and 0.3mm-0 with studs surface was 58.36% and 21.7%.

These intelligently engineered units are ideal for classifying coarser cuts ranging from 50 to 200 mesh. The feed material is dropped into the top of the classifier. It falls into a continuous feed curtain in front of the vanes, passing through low velocity air entering the side of the unit. The air flow direction is changed by the vanes from horizontal to angularly upward, resulting in separation and classification of the particulate. Coarse particles dropps directly to the product and fine particles are efficiently discharged through a valve beneath the unit. The micro fines are conveyed by air to a fabric filter for final recovery.

Air Magnetic Separation Cluster is a special equipment developed for dry magnetic separation of fine size (-3mm) and micro fine size(-0.1mm) magnetite. The air magnetic separation system can be combined according to the characteristic of magnetic minerals to achieve effective recovery of magnetite.

After rough grinding, adopt appropriate separation method, discard part of tailings and sort out part of qualified concentrate, and re-grind and re-separate the middling, is called stage grinding and stage separation process.

According to the characteristics of the raw ore, the use of stage grinding and stage separation technology is an effective measure for energy conservation in iron ore concentrators. At the coarser one-stage grinding fineness, high-efficiency beneficiation equipment is used to advance the tailings, which greatly reduces the processing volume of the second-stage grinding.

If the crystal grain size is relatively coarse, the stage grinding, stage magnetic separation-fine sieve self-circulation process is adopted. Generally, the product on the fine sieve is given to the second stage grinding and re-grinding. The process flow is relatively simple.

If the crystal grain size is too fine, the process of stage grinding, stage magnetic separation and fine sieve regrind is adopted. This process is the third stage of grinding and fine grinding after the products on the first and second stages of fine sieve are concentrated and magnetically separated. Then it is processed by magnetic separation and fine sieve, the process is relatively complicated.

At present, the operation of magnetic separation (including weak magnetic separation and strong magnetic separation) is one of the effective means of throwing tails in advance; anion reverse flotation and cation reverse flotation are one of the effective means to improve the grade of iron ore.

In particular, in the process of beneficiation, both of them basically take the selected feed minerals containing less gangue minerals as the sorting object, and both use the biggest difference in mineral selectivity, which makes the two in the whole process both play a good role in the process.
