the 7 most useful manganese ore beneficiation methods | fote machinery

The data recorded by Statistics in 2020 shows that although in 2019 manganese ore price fell to the bottom, the price in 2020 still gets increased to 4.5 U.S. dollars per metric ton unit CIF even under the impact of COVID-19. Manganese ore prices are forecast to remain at global prices by 2020 over the next two years, which is good news to manganese ore suppliers.

Besides, Justin Brown, managing director of Element 25said Manganese has the traditional end uses in steel, and that market is fairly stable". As people's demand for laptops and electric cars increases, the output of lithium batteries has also soared, and the most important element in lithium batteries is manganese.

Manganese ore after the beneficiation process is applied in many respects in our daily lives. Of annual manganese ore production, 90 percent is used in steelmaking, and the other 10 percent is used respectively in non-ferrous metallurgy, chemical industry, electronics, battery, agriculture, etc.

In the metallurgical industry, manganese ore is mostly used for manganese-forming ferroalloys and manganese metal. The former is used as deoxidizers or alloying element additives for steelmaking, and the latter is used to smelt certain special alloy steels and non-ferrous metal alloys. Manganese ore can also be used directly as an ingredient in steelmaking and ironmaking.

When smelting manganese-based iron alloys, the useful elements in manganese ore are manganese and iron. The level of manganese is the main indicator for measuring the quality of manganese ore. The iron content is required to have a certain ratio with the amount of manganese.

Phosphorus is the most harmful element in manganese ore. The phosphorus in steel reduces the impact of toughness. Although sulfur is also a harmful element, it has a better desulfurization effect during smelting, and sulfur is volatilized into sulfur dioxide or enters the slag in the form of calcium sulfide or manganese sulfide.

In the chemical industry, manganese ore is mainly used to prepare manganese dioxide, manganese sulfate, and potassium permanganate. It is also used to make manganese carbonate, manganese nitrate and manganese chloride.

Since most manganese ore is a fine-grained or fine-grained inlay, and there are a considerable number of high-phosphorus ore, high-iron ore, and symbiotic beneficial metals, it is very difficult to beneficiate.

At present, commonly used manganese ore beneficiation methods include physical beneficiation (washing and screening, gravity separation, strong magnetic separation, flotation separation, joint beneficiation), chemical beneficiation (leaching method) and fire enrichment, etc.

Washing is the use of hydraulic washing or additional mechanical scrubbing to separate the ore from the mud. Commonly used equipment includes washing sieves, cylinder washing machines and trough ore-washing machine.

The washing operation is often accompanied by screening, such as direct flushing on the vibrating screen or sifting the ore (clean ore) obtained by the washing machine to the vibrating screen. Screening is used as an independent operation to separate products of different sizes and grades for various purposes.

At present, the gravity separation is only used to beneficiate manganese ore with simple structure and coarse grain size and is especially suitable for manganese oxide ore with high density. Common methods include heavy media separation, jigging and tabling dressing.

It is essential to recover as much manganese as possible in the gravity concentration zone because its grinding cost is much lower than the manganese in the flotation process, and simple operations are more active.

Because of the simple operation, easy control and strong adaptability of magnetic separation can be used for dressing various manganese ore, and it has dominated the manganese ore dressing in recent years.

Gravity-magnetic separation plant of manganese ore mainly deals with leaching manganese oxide ore, using the jig to treat 30~3 mm of cleaned ore can obtain high-quality manganese-containing more than 40% of manganese. And then can be used as manganese powder of battery raw material.

The jigging tailings and less than 3 mm washed ore are ground to less than 1mm, and then being processed by strong magnetic separator. The manganese concentrate grade would be increased by 24% to 25%, and reaches to 36% to 40%.

Adopting strong magnetic-flotation desulfurization can directly obtain the integrated manganese concentrate product; the use of petroleum sodium sulfonate instead of oxidized paraffin soap as a collector can make the pulp be sorted at neutral and normal temperature, thus saving reagent consumption and energy consumption.

The enrichment of manganese ore by fire is another dressing method for high-phosphorus and high-iron manganese ore which is difficult to select. It is generally called the manganese-rich slag method.

The manganese-rich slag generally contains 35% to 45% Mn, Mn/Fe 12-38, P/Mn<0.002, and is a high-quality raw material to manganese-based alloy. Therefore, fire enrichment is also a promising method for mineral processing for low-manganese with high-phosphorus and high-iron.

Manganese ore also can be recovered by acid leaching for production of battery grade manganese dioxide for low-manganese ores. Leaching of manganese ore was carried out with diluted sulphuric acid in the presence of pyrite in the temperature range from 323 to 363 K.

After processed by hydraulic cone crusher, the smaller-sized manganese ore would be fed to grinding machine- ball mill. It can grind the ore to a relatively fine and uniform particle size, which lays a foundation for further magnetic separation of manganese ore.

It is indispensable grading equipment in the manganese ore beneficiation plant. Because by taking advantage of the natural settling characteristics of ore, a spiral classifier can effectively classify and separate the manganese ore size to help control the amount of grinding required.

The flexibility of flotation is relatively high. You can choose different reagents according to the type and grade of the ore. Although the entire process of froth flotation is expensive, it can extract higher-grade manganese ore.

The magnetic separator is a highly targeted magnetic separation device specially developed for the properties of manganese ore. The device not only has the advantages of small size, lightweight, high automation, simple and reasonable structure, but also has high magnetic separation efficiency and high output.

Ore beneficiation plant, also called ore extracting plant, separating plant, concentrating plant, refining plant, leaching plant, or mining plant, is the necessary part for every mining work of metallic ores.

For miners, they care about the cost and reliability of plant. Before describing the plant cost, lets see the manganese ore kinds first. According to the different kinds, FTM Machinery engineers adopt different ways.

Manganese oxide ore is mainly found on the mineral deposites by weathering, and some on sedimentary and hydrothermal deposits. There are three kinds of manganese oxide, respectively called psilomelane, pyrolusite and manganite, etc.

The extraction process of manganese oxide gives priority to gravity separation. Weathered manganese oxide often contains a lot of mud and powder, so its refining work adopts the washing and gravity separation way.

The raw ore are washed first to remove mud off, then some can be directly used as concentrates, some needs to be dressed again by jigger and shaking table. During the washing process, some ores may overflow and they need to be further recycled by the methods of gravity separation or strong magnetic separation.

In the ferric manganese oxides, limonite contains. It is hard to separate limonite with manganese by the ways of gravity separation, flotation separation or strong magnetic separation. We need to use the way of roasting-magnetic separation and it has already been used for industrial applications.

In the sedimentary carbonate manganese, the major ores are rhodochrosite, manganocalcite, manganese-bearing calcite and oligonite, etc and the gangue are silicates and carbonates, often accompanying with foreign matters like sulfur and iron elements.

Carbonate manganese ore mining process is rare to be found on mining area. But, it still exists. To process the sedimentary carbonate manganese ore, FTM engineers adopt the flotation separation, in order of carbonaceous shale, pyrite and manganese.

To the hydrothermal carbonate manganese ore accompanying with zinc and lead, engineers of FTM Machinery often adopt the method of flotation and strong magnetic separation. For some carbonate manganese with sulfur inside, engineers use the way of roasting to get rid of sulfur.

Elements like iron, sulfur or gangue in manganese oxide and carbonate manganese are hard to be extracted, since their size is very fine. Based on this situation, FTM engineers take the way of smelting.

In comparison with the one-time separation, magnetic separation is more effective in improving the recovery rate from 72.01% to 89.24%. Based on the experiments, FTM engineers design the manganese ore extracting plant as below.

The mined manganese ore is transported to field by trucks and the size is generally smaller than 350mm. Piled in the bin by loader, mined manganese ore are fed into jaw crusher by belt conveyor, then to vibrating screen for size screening with 0-10mm and >10mm.

To the ores with size of 0-10mm, they are conveyed to another bins, waiting for being dressed. For the remains with size larger than 10mm, they are conveyed back to jaw crusher for being crushed and screened again until the size meets the requirement for dressing work.

Through the hopper, 0-10mm crushed manganese ore enter into NO.1 magnetic separator and NO.2 magnetic separator. The extracted ore are transported to concentrates field by belt conveyor and the tailing is conveyed to NO.3 magnetic separator of DPMS-300mmX1800mm by belt conveyor for being extracted again. At last, concentrates are in concentrates field and tailing is in tailing field.

The price of manganese ore leaching(beneficiation) plant scope varies from 900-95000 us dollars. The price is affected by the following factors like mining situation, demands of customers, machine model, raw ore elements, etc. Leave your demands on our website for the detailed Price quotation.

The top five manganese mining countries in the world include South Africa, Australia, China, Gabon and Brazil. Historically, the demand for manganese has increased following the production of steel and it is expected that this will also be the case in the future.

The following figure shows the global output of different grades of manganese ore. Thelow-grade manganese ore accounts for a large proportion, so the manganese ore beneficiation technology, which is very important for low-grade manganese ore, will be introduced in the next part.

Low-grade manganese ore cannot be directly used in industrial production due to high impurity content, thus there is a need for a method of enriching low-grade manganese ore. Manganese ore processing plant is used to separate valuable minerals from impurity content by physical or chemical properties.

Based on these differences, the suitable processing plant for manganese ore is the mechanical selection (including washing, sieving, re-election, strong magnetic separation and flotation), as well as fire enrichment and chemical beneficiation.

There are many types and sizes of equipment in the whole manganese beneficiation process. The major equipment is as follows: vibrating feeder, PE jaw crusher, cone crusher, vibrating screen, pendulum feeder, ball mill, spiral classifier, high frequency sieve, magnetic separator, concentrator, filter, dryer, etc.

The general process of the manganese processing plant is like this: crushing process grinding process separation process, ie manganese ore vibration feeder jaw crusher cone crusher vibrating screen pendulum feeder ball mill spiral separator magnetic separator and so on.

Equipment Practical applications Jaw crusher Be used for primary crushing of manganese ore, which will be broken into particle size less than 35 mm Cone crusher Be used for secondary crushing of manganese ore to produce fine grade manganese to under 15 mm Ball mill Grind manganese ore into powder Spiral separator Granular grading of manganese ore slurry in metal beneficiation process below 0.075 mm Magnetic separator Separate the magnetic material in the mixture by magnetic force and mechanical force according to the difference in the specific magnetic coefficient of the mineral Spiral chute Sort manganese ore fines with a particle size of 0.3--0.02 mm

manganese ore beneficiation | manganese ore processing plant

Manganese ore is widely used in steel, non-ferrous metallurgy, chemical, electronics, battery, agriculture, etc. industry. More than 90% of the worlds manganese is used in the steel industry. Global terrestrial manganese ore reserves are 6. 800 million tons (manganese metal), most of which is manganese oxide ore, with a production of 16 million tons (manganese metal) in 2017. spent catalyst could be a secondary recover resource of manganese. Chinas manganese ore resources are mainly manganese carbonate ore, and the average grade of ore is only 21. 4%. With the consumption of manganese ore resources, the grade of ore is gradually reduced, which is not only difficult to develop and utilize but also has a large amount of smelting wastewater and waste slag. Therefore, improving manganese resource utilization technology level is of great significance for realizing the conservation and utilization of manganese resources, protecting the ecological environment and promoting the sustainable development of the manganese industry.

The purpose of manganese ore beneficiation is to remove the slime, separate stone and mineral manganese, enrich the low-grade ore, improve the ore grade, reduce the energy and reagent consumption of the smelting process from the source, and then reduce the amount of smelting waste. The methods of mineral manganese processing mainly include washing, gravity separation, strong magnetic separation, flotation, fire enrichment and chemical beneficiation.

There is a large difference in density between useful minerals and gangue minerals, and the density of manganese oxide ore is 3.7 ~ 5g/cm3, the density of manganese carbonate ore is 3.3 to 3.8 g/cm3, the density of gangue minerals such as quartz and calcite is 2.6 to 2.9 g/cm3. The use of re-election technology can achieve the separation between useful manganese ore and gangue minerals, and achieve the purpose of enriching manganese ore to enhance ore grade. The gravity separator equipment mainly includes jig, shaker table and heavy medium hydro-cyclone. For the treatment of manganese ore, a jig and a shaker were used respectively, and the recovery rate of the MnO obtained by the re-selection of the jig was 51. 54%, the recovery rate of shaker gravity separation was 91. 11%

Manganese ore is mostly weakly magnetic. The specific magnetization coefficient of the manganese ore is up to 250106cm 3/g, the tungsten manganese iron ore is 66106 cm3/g, and the manganese carbonate ore is 125106 cm 3/g. Most of the gangue minerals are aluminosilicates, which are non-magnetic. Therefore, manganese ore enrichment can be achieved by strong magnetic separation. The magnetic separation of low-grade manganese ore was studied. After two-step magnetic separation with high magnetic field strength and low magnetic field strength, the ore grade was increased to 45. 8%. The main types of magnetic separators are the high-density magnetic separator, wet magnetic separator, dry magnetic separator.

Flotation is suitable for the treatment of fine-grained manganese ore. Ore size is an important indicator affecting the flotation effect. The development of flotation reagents is the key technology. Traditional flotation collectors mainly include oleic acid, oxidized paraffin soap, naphthenic acid and tart oil. flotation machine for sale.

The natural type of Australia manganese ore is mainly manganese oxide ore, which has two types: primary and oxidized. Manganese minerals mainly include pyrolusite, hard manganese ore, crypto-potassium-manganese ore, and a small amount of manganese earth, black manganese ore, manganese ore, strontium magnesium manganese ore, black zinc manganese ore, galvanized manganese ore and limonite. The gangue minerals are mainly quartz, followed by kaolin, sericite, opal, stone pulp, clay and so on. Australia manganese ore primary manganese ore is only found in sedimentary-reformed deposits, mainly composed of manganese carbonates, sulfides and silicates. The ore type is mainly composed of mixed primary manganese ore, and can be divided into sulphur manganese ore-manganese carbonate ore, sulphur manganese ore-manganese silicate-manganese carbonate ore. Manganese minerals are mainly rhombohedral, sulphur-manganese or eutropha, with a small amount of iron-sulfur-manganese ore, calcium sulphurite and manganese garnet; associated metal minerals such as galena, sphalerite, strontium silver ore Copper ore and pyrite. The gangue minerals are mainly quartz, calcite and chlorite, a small amount of diopside, serpentine and claystone.

For the washing of the manganese, spiral washer or log washer can be involved to remove mud or clay in the manganese ore. Spiral washer is suitable for manganese of -50mm while rotary screen is mainly for big manganese blocks.

After washing, crusher will be needed to make the manganese smaller. The crushed manganese has a large size range of 0-50mm. Of course, if the manganese grains are not liberated or dissociated from the gangue, the ore need further crushing or milling to be finer to liberate or dissociate the manganese granules from the impurities.

The core manganese beneficiation plant is mainly Gravity Separation and Intensive Magnetic Separation. This process of manganese ore beneficiation is fairly easy. Presently, gravity separation is simply right for sorting manganese with simple structure, and particularly manganese oxide with superior density. And the gravity separation machine is mainly manganese jig machine with washing-box. There are several models of manganese like LTA1010/2 sine wave jigging concentrators, 2LTC6109/8T trapezoidal jigging machine, AM30 manganese jig separator, and 2LTC912/4 manganese jig beneficiation plant. LTA1010/2, and 2LTC6109/8T trapezoidal jigging machines are for manganese ore of 0-8mm, AM30 manganese jig separators are mainly for manganese mineral of 8-25mm, and 2LTC912/4 manganese jig beneficiation plants are mainly for manganese of 25-50mm.
