Gravity separation and magnetic separation can be involved for manganese upgrading. Gravity separation is more commonly used in manganese beneficiation with its low plant investment and low operation cost. However for some manganese ore of too fine inlay or small density difference between manganese and its attached gangue, gravity separation can not work, magnetic separation or floatation separation can be considered. In this situation, magnetic separation can be the main beneficiation way for manganese ore because floatation separation needs large investment and high operation cost and it is hard to be accepted by the miner. Intensity magnetic separation can be the core upgrading method for this kind of manganese ore. The following is about Forui manganese magnetic separator.

manganese ore processing equipment to wash manganese ore

Manganese washing is to separate the useful manganese from impurities to upgrade the manganese on effect of water washing force, mechanical force, and self-brasive force. The main factors to influence the washing efficiency are the physical nature of the clay, the mineral natures, the force strength of mechanical part. The washing plant for manganese ore can be spiral washer, slotted washer, vibrating screen, rotary washer.

Gravity separation, magnetic separation, and floatation separation can be used for manganese beneficiation. For manganese oxide ore, the main beneficiation method is gravity concentration. As we all know the manganese is kind of mineral with weak magnetism, so if magnetic separator is used, intensity magnetic separation machines can be ok, and the treatment capacity shall be limited and the investment shall be higher. Floatation concentration can be involved when it comes to manganese ore of fine grain inlay, but in most situation, floatation separation is not adopted because of the chemicals involved and high operation cost.

About the most common upgrading method of gravity concentration, the jigging separator machines, spiral washer plant, and concentrating table can be involved according to the natures of the ore. Here Forui manganese jigging concentration equipment can deal with manganese of 0-50mm with combination of several jiggers with different feeding size ranges.

manganese mining solution - mineral processing

manganese mining solution - mineral processing

Manganese is widely distributed in nature, and almost all kinds of ores and silicate rocks contain manganese. In modern industry, manganese and its compounds are widely used in various economic fields, of which the iron and steel industry is one of the most important fields. The amount of manganese used is as high as 90%-95%, which is mainly used as a deoxidizer and desulfurizer for iron and steelmaking.

Manganese oxide oreManganese oxide ore is mainly composed of secondary manganese oxide ore of weathered deposits, in addition to some primary and secondary manganese oxide ore of sedimentary and hydrothermal deposits. The manganese minerals in the manganese oxide ore are mainly dolomite, pyrolusite and hydromanganese ore; the gangue minerals are mainly silicate and carbonate minerals, often accompanied by iron, phosphorus and nickel, cobalt and other components.

Manganese carbonate oreThe manganese minerals in sedimentary manganese carbonate ore mainly include rhodochrosite, calcium rhodochrosite, manganese-containing calcite and rhodochrosite; gangue minerals include silicate and carbonate minerals, often accompanied by impurities such as sulfur and iron. The ore is generally more complex, and the particle size of the manganese mineral inlay is as fine as micrometers, which is not easy to dissociate, and it is often difficult to obtain a higher concentrate grade.

Because most manganese ores are fine-grained or fine-grained, and there are a considerable number of high-phosphorus ores, high-iron ores and symbiotic (associated) beneficial metals, it is very difficult to classify. At present, the commonly used manganese ore beneficiation methods include physical beneficiation (washing and screening method, gravity separation method, strong magnetic separation method, flotation method, combined beneficiation method), chemical beneficiation (leaching method) and special beneficiation (fire method enrichment method) ).

Ore washing mainly uses mechanical scrubbing machine to separate the ore from the mud. Commonly used equipment includes ore washing sieve, cylindrical ore washing machine and trough ore washing machine. Usually, the ore washing operation is accompanied by the sieving operation. Directly flush the water on the vibrating screen or send the ore (net ore) obtained by the ore washing machine to the vibrating screen for screening. Screening can be used as an independent part to separate products of different particle sizes and grades for different uses.

At present, the gravity separation method is only suitable for sorting manganese ore with a simple structure and coarser particle size, especially manganese oxide ore with a higher density. Commonly used gravity separation methods include heavy-medium beneficiation, jig beneficiation and shaker beneficiation.The beneficiation process of manganese oxide ore is generally to crush the ore to 6-0mm or 10-0mm, and then to classify, coarse grade particles are sent to jig sorting, and fine grade particles are sent to shaker for sorting.

Manganese minerals are weak magnetic minerals (specific magnetization coefficient X=1010-6~60010-6cm3/g), can be effectively recovered in a strong magnetic field magnetic separator with a magnetic field strength of Ho=800-1600kA/m (10000-20000oe), and the grade of manganese can generally be increased by 4-10%.Because the magnetic separation method has the characteristics of simple operation, easy control, and strong adaptability, it is widely used in the selection of various manganese ores, and various new coarse, medium, and fine-grained strong magnetic machines have also been successfully developed.

The strong magnetic-flotation method has good adaptability. The strong magnetic separator not only effectively removes the slime, but also improves the selection grade of flotation. Strong magnetic-flotation desulfurization can directly obtain comprehensive manganese concentrate products.Sodium petroleum sulfonate instead of oxidized paraffin soap as collector can make the ore pulp sort at neutral and normal temperature, saving medicine consumption and energy consumption.

Generally, manganese ore leaching methods include direct leaching, roasting leaching and biological leaching. Among them, the direct leaching method includes the hydrosulfite method, sulfur dioxide method, ferrous sulfate method and so on.Taking the leaching method of sulfur dioxide for manganese as an example, the manganese ore is slurried, and sulfur dioxide gas is introduced, and the manganese oxide in the ore is converted into MnSO4 and MnS2O6. Lime milk is added to the filtrate to produce manganese hydroxide precipitation, and solid manganese hydroxide is obtained after filtration. This method is suitable for processing low-grade, inlaid fine-grained manganese oxide ores.

The above are common manganese ore beneficiation methods. In actual production, most of the manganese carbonate ore beneficiation methods use strong magnetic separation, heavy medium beneficiation method and flotation method.The manganese oxide ore is mainly adopts gravity separation method, and the ore washing-heavy separation-reduction roasting-magnetic separation-heavy separation process flow is mostly used. Of course, it is often necessary to combine two or more beneficiation methods for refractory manganese ore.

About manganese processing equipment, it means both manganese ore washing equipment and manganese ore beneficiation plant. However, sometimes manganese ore washing machines are the same with manganese beneficiation or processing equipment.

Manganese ore washing machine is to wash the manganese ore with large quantity of sticky clay or mud avoiding cohering of ore blocks and improving a little about manganese grade. This kind of ore washing machine can be also involved when manganese ore is mixed with kaoline. There are Cylinder ore washer and slot ore washer.

Cylinder ore washer is used when the ore is too sticky and hard to wash. It can be fed with large size with its high efficiency. Slot ore washer is usually used to wash the ore with normal sticky clay and small quantity clay with its small investment, high washing efficiency. The following are pictures of both ore washers:

Manganese ore beneficiation processing machine is also called manganese washing machine in many countries. So in many places, manganese beneficiation machines are called manganese ore washing machine to upgrade the grade of Mn in manganese ore. The simple washing machines can improve the manganese grade, however, the improving grade can be limited and can not meet the need of market. In order to get high grade manganese concentrate, not only ore washer but also the relative beneficiation machines are involved.

The most common manganese ore beneficiation machines are gravity separation equipment-manganese jig concentrator. Manganese jig machine can help to remove the intergrowth gangue to upgrade the manganese. Manganese jig separator can separate manganese of a large size range with its good concentration efficiency and high recovery rate. This kind of manganese upgrading separators has been widely used to get manganese concentrate of 0-8mm, 8-30mm, even 30-50mm. The following pictures are about the jiggers for manganese of 0-8mm, 8-30mm, 30-50mm.

Manganese jig machine can help to get fine, medium, and coarse manganese concentrate with its high recovery and wide adoptability. And the following is about the beneficiation efficiency of manganese ore test by jigging separators:

Forui, a professional manufacturer of kinds of mining machines, has rich ore beneficiation experience to share with you and mini test can be done for you free if samples can be available. Related Information:

Product Introduction Magnetic separator is one of the most widely used and versatile machines in the industry. It is suitable for the separation of magnetic substances with different magnetic properties. It is widely used in resource recovery, mining, timber, kiln, chemistry, food and other industries. For mining industry, the magnetic separator is suitable for wet or dry magnetic separation of manganese ore, magnetite, pyrrhotite, roasted ore, ilmenite, hematite limonite and other materials with particle size less than 2-3mm. It is also used for iron removal of coal, non-metallic ore, building materials and other materials.

Classification Type of magnet: Permanent magnetic separator , electromagnetic iron separator Drying and wetting of ore: Dry magnetic separator, wet magnetic separator Magnetic system: Drum magnetic separator, roller magnetic separator, drum roller magnetic separator, flat plate magnetic separator. Classification of magnetic system: Open magnetic separator, closed magnetic separator Number of magnetic system: Single drum magnetic separator, double drum magnetic separator, combined multi drum magnetic separator. Classification of feeding mode: Upper feeding magnetic separator, lower feeding magnetic separator. Classification of magnetic field intensity: Low intensity magnetic separator, medium intensity magnetic separator, high intensity magnetic separator. Different structure of the tank: downstream, countercurrent and semi countercurrent. The particle sizes of three different types of magnetic separators are as follows: downstream tank 6 mm, countercurrent tank 1.5 mm and semi countercurrent tank 0.5 mm.

The downstream magnetic separator has large processing capacity. It is suitable for roughing and cleaning of strong magnetic materials with coarser particle size. It can also work in series. When the feed volume of the downstream magnetic separator is large, the magnetic particles are easy to lose in the tailings, so the operation management should be strengthened to control the lower pulp level.

Countercurrent magnetic separator is suitable for roughing and scavenging of fine strong magnetic minerals with high recovery but low concentrate grade. Because the coarse-grained materials are easy to deposit and block the separation space, the counter current magnetic separator is not suitable for processing coarse-grained materials.

Semi countercurrent magnetic separator can obtain high quality iron concentrate and good recovery, so semi countercurrent magnetic separator is widely used in production practice. It is suitable for the roughing and cleaning of ore particles less than 0.5mm. It can also be used in series or parallel to realize multiple sweeping and cleaning.

Our Magnetic Separators We have a lot of magnetic separation equipments. Mainly introduce 3 types: wet drum magnetic separators, high intensity magnetic separators and 3 PCS disk dry magnetic separators.

High Intensity Magnetic Separators: High intensity magnetic separator is a kind of high intensity magnetic separation equipment for separating weak magnetic minerals. It is also called super strong magnetic separator. It can be divided into dry and wet separator. It is a general term for magnetic separators with magnetic field of 10000-16000gs or more.

3 PCS Disk Dry Magnetic Separators: The three disc dry magnetic separator is suitable for separation of mixed ores of various magnetic minerals. It is mainly used for dry selection of titanium, rare earth, tungsten tin, chromite, niobium tantalum, limonite, zircon, rutile, solitary residence and so on.

Magnetic separator is mainly used to select wet weak magnetic field and remove the strongly magnetic minerals of fine grains. They are widely used in mineral processing industry, coal washing industry, chemical industry, etc, e.g. recycle heavy formulas such as magnetic heavy media during heavy media separation, concentrate low-concentration slurry in iron ore and gather magnetic steel minerals, treat ore feeding from high-intensity magnetic separators, remove magnetic or weakly magnetic ores and coenobium, as well as prevent blockage of magnetic media.

Magnetic separator can be divided into two kind : roller magnetic separator and cylinder magnetic separator. cylinder type magnetic separator whose diameter is less than 500mm, the magnetic intensity can made from 800 gauss to 9500 gauss. cylinder type magnetic separator whose diametere is from 500mm to 1200mm,the max magnetic intensity is 5000 gauss. the diameter size of roller type can made from 100mm to 600mmm. the max Magnetic strength available is : 16000 gauss the diameter size of roller type separator is : 100-140-160-180-220-240-300-320-380 the magnetic strenth of roller type is among 8000 gauss and 16000 gauss

The diameter and length of the magnet roller are customer-made. In fact, the use of the effect is generally more than 150 will be better The larger the magnet, the higher the throughput The longer the length, the greater the handling capacity, this is customized according to customer requirements. The thickness of our magnetic block is 25mm, is a circular disk Disk and disk have gaps About 3-4mm gap

Magnetic separation is an effective mineral processing method to separate the minerals based on the magnetism difference. Magnetic separator machine can effectively select a large number of magnetic minerals, such as magnetite, hematite, limonite, manganese siderite, wolframite, ilmenite, manganese ore, manganese carbonate, metallurgical manganese ore, iron ore, kaolin, manganese oxide ore, rare earth ore.

Wet type? Fine particle and coarse particle? Strong magnetic? . . How many kinds of magnetic separators equipment? Frankly, there are many classification methods of magnetic separator types, join us to solve the puzzle.

According to the state of the material, the magnetic separator is divided into dry type magnetic separator and wet type magnetic separator. Dry magnetic separator refers to the material keep dry, dont need to mix with water in the magnetic separation process. The material for wet magnetic separator must be mixed with water or other media.

The dry magnetic separator generally does not need a tank for accommodating the slurry, and the material is conveyed by a vibrating feeding device, and a dustproof device is often provided. The wet magnetic separator has a tank to accommodate the slurry to maintain the fluidity of the material, and the pump is usually transported by a slurry pump.

Dry magnetic separation function for bulk, coarse particle separation, but also fine mineral separation, while wet magnetic separator can not sort large bulk minerals, most are effective for fine or even fine particles, except for a few models that can select coarse particle. HGMS (high gradient wet magnetic separator) can sort micron-sized materials using a suitable magnetically permeable medium.

Dry magnetic separator requires low water content, dry materials, good liquidity, do not adhesion, agglomeration. The wet magnetic separation operation has certain requirements on the slurry concentration. There is no obvious limit on the concentration of coarse magnetic separation, but the material concentration should not be too low to effectively control the negative fluid force during the mineral processing operation. When magnetically selecting fine particles, the concentration is required to be high to ensure the recovery of magnetic minerals.

Dry weak magnetic separators have features like a simple process, low investment, low water consumer. However, the bottleneck of the dry cylinder magnetic separator is that the dust is difficult to control, so as the environmental protection requirements become stricter, the dry type magnetic separation is gradually replaced by the wet weak magnetic separator. At present, the fine-grained dry magnetic separation machine is only used in the water shortage area and severe cold area.

According to the magnetic field strength, magnetic separator is divided into three types: weak magnetic separator (low intensity magnetic separator), medium magnetic separator and strong magnetic separator (high intensity magnetic separator). The weak magnetic separator is from several hundred to 3000 Gs; the strong magnetic separator generally refers to 3000Gs to 6000 Gs, and the medium magnetic field magnetic separator between the two.

The reason why it is classified according to the strength of the magnetic field is related to the magnetic properties of various common minerals (another post Magnetic Mineral Classification). However, it is necessary to know that there is no absolute standard for different magnetic strength and their matched equipment.

In the actual magnetic separation machine, the magnetic field strength ranges from hundreds of Gauss to 20,000 Gauss, some even exceed 20,000 Gauss, but it is rarely used in general beneficiation production. Excessive magnetic field strength will lead to weak magnetic minerals to agglomerate that is not conducive to beneficiation. So the upper limit of the magnetic field strength of the strong magnetic separator is 20000Gs.

On the working surface of various magnetic separators, the magnetic field strength varies at different points and in different ranges, and the working magnetic field is a non-uniform magnetic field. Generally, the value of the magnetic field strength expressed refers to Max. magnetic strength, some factories may list the average value.

According to the type of magnetic field, the magnetic separator is divided into permanent magnet magnetic separator and electromagnetic magnetic separator. The permanent magnet magnetic separator uses a permanent magnet material such as ferrite or neodymium iron boron to generate a working magnetic field, and the electromagnetic magnetic separator uses a magnet with a yoke, a solenoid, and a magnet to generate a magnetic field.

The magnetic field strength of the permanent magnet magnetic separator is fixed, but the different action areas in the magnetic separation working surface can be designed to have different magnetic field strengths. The electromagnetic magnetic separator can adjust the whole magnetic field, but the magnetic field strength values in the working surface are a balanced, uniform magnetic field.

The magnetic energy of the permanent magnet magnetic separator is low, while the electromagnetic separation requires high energy consumption to generate the excitation current. The energy consumption per unit of the permanent magnetic separator is much lower than that of the electromagnetic magnetic separator.

According to the structure of the main working part of the magnetic separator, it is divided into cylindrical (drum) magnetic separator, roller magnetic separator, disc magnetic separator, ring magnetic separator, in addition, have rotor magnetic separator, belt magnetic separation, conical magnetic separator, but these types of magnetic separators have been used less.

According to the way the magnetic field strength changes: 1) Constant magnetic field magnetic separator. Using a permanent magnet material and a direct current electromagnet, a solenoid, or the like as a magnetic source, the magnitude and direction of the magnetic field strength do not change with time. 2) Alternating magnetic field magnetic separator. An electromagnet that is connected to an alternating current is used as a magnetic source. The magnitude and direction of the magnetic field strength changes over time. 3) Pulsating magnetic field magnetic separator. An electromagnet that simultaneously transmits direct current and alternating current is used as a magnetic source. The magnitude of the magnetic field varies with time, but the direction does not change. And pulse Similar to the dynamic magnetic separator, the use of pulsating water flow causes the slurry to pulsate, affecting the sorting force of the magnetically selected mineral. 4) Rotating magnetic field magnetic separator. A magnet is used as the magnetic source, and the magnetic pole rotates around the axis. The magnitude and direction of the magnetic field strength changes over time.

According to whether the magnetic mineral is reversed in the magnetic field of the magnetic separator, it is divided into a mineral reversal magnetic separator and Nonreversal magnetic separator. The mineral reversal magnetic separator can effectively improve the concentrate grade, and the Non-reversal magnetic separator can select the refractory weak magnetic minerals.

According to the minerals, it also can divide into such as magnetite magnetic separator, hematite magnetic separator, manganese ore magnetic separator, quartz sand magnetic separator, NdFeB magnet, nickel, etc.

In addition to the types listed above, there are many ways to classify magnetic separators. Although each manufacturer has a self-classification method, it lacks standards. In the magnetic separator model selection stage, most prefer using mixed name, such as the hematite wet magnetic separator, actually indicate that the sorting mineral is hematite, and the ore dressing method is wet type, but does not show us whether the magnetic separator is a permanent magnet type or an electromagnetic type, and neither indicate which magnetic separation structure the equipment is.
