Introduction: Fote specialists proceed a deep investigation toward the working pit, make a study to the mineralogical features of lead-zinc ores, optimizes the traditional ore-dressing technology and finally designs a 80t/h dressing plant.
Zinc ore is a widely-used mineral in industries of electrical engineering, mechanism, metallurgy, chemical engineering, light industry, military , and medicine, etc. Countries which own a higher proportion of zinc ore include Canada, India, China, Argentina, Mexico, and Brazil, etc. Generally, we use the technology of flotation separation for dressing zinc ore.
Argentina, located in the north part of South America, has a quite complex and diverse terrain. Fote specialists proceed a deep investigation toward the working pit, makes a study to the mineralogical features of lead-zinc ores, optimizes the traditional ore-dressing technology and finally designs a 80t/h dressing plant. This selection main includesPE600900 jaw crusher, PF1520 impact crusher, 40006700 ball mill, SF flotation cell, etc. After the five processes of crushing, grinding, classifying, flotation and drying, the recycling rate of this plant reaches to 60% higher and every index is in demand.
1: good energy-conserving effect: flotation machine is the core equipment of the whole plant and its energy-conserving effect reaches to 70% higher. The recycling use of water resource can be effectively realized and energy consumption reduces a lot.
If your machine fails, production at the entire plant will be at risk. To avoid such losses, you can get critical replacement parts of the machine whenever you need it.
The Mineral Processing Flowsheets shown on the following pages are based on actual data obtained from successful operating plants. Metallurgical data are shown in these flowsheets which incorporate Crushers, Grinding Mills, Flotation Machines, Unit Flotation Cells, and Selective Mineral Jigs as well as other standard milling equipment.
The Flotation Machine, the Selective Mineral Jig and the Unit Flotation Cell have revolutionized flowsheet design and have made it possible for both small and large plants to increase recoveries and economical return.The Unit Flotation Cell and the Selective Mineral Jig have been perfected to meet the most important principle in ore dressing.
To recover this free mineral, either the Unit Flotation Cell or Jig or both can be installed in the grinding circuit without auxiliary equipment such as pumps or elevators, and for successful operation do not usually require more water than necessary for classifier dilution.
Many of the flowsheets given here have been made possible because of the fact that a coarse pulp (particles as coarse as 1/4)can be circulated in the Sub-A Flotation Machine without sanding or choke-ups and with high metallurgical efficiency.
Sub-A Flotation Machines have the gravity flow principle and flexibility that has made possible the development and application of many of these flowsheets. In fact, the elimination of pumps in handling concentrates for cleaning and recleaning has simplified flowsheets and reduced operating expenses to the operators advantage and profit. It should be pointed out that it is not only the cost of pump wearing parts but the time lost in shut-down for pump repair that is important in profitable mill operation.
Ore Testing takes the guesswork out of answering the question of can this ore be milled profitably. It also gives conclusive answers to the subordinate- questions of what type of flowsheet will give the greatest net return on this operation, and can increased value and/or increased mill capacity be obtained by the addition or substitution of equipment in the mill?
In other words, ore testing is the key to the basic question of the economic possibility of a mining operation. It gives the answer to this question at a minimum of expense without making a costly investment in equipment to learn it the hard way.
The results obtained through ore testing and the intelligent interpretation of the results very often lead to a simple method of treatment giving good profits, where some other treatment might mean less profit or an actual deficit. Our Labgives a good illustration of what proper selection of treatment methods based on ore testing can result in. Test results give you facts.
The 911MPEProcess Equipment Ore Testing Laboratory is continually being confronted with and solving such problems. Very often situations arise where the most common methods of treatment may not be successful but little known and ingenious methods may be applied. The flowsheet showed the results obtained from testing a complex lead-zinc-copper-iron ore containing values in gold. Exceptionally high grade and recovery were obtained in this instance. Utilizing a patented process special reagents made profitable production of lead/copper and zinc-iron concentrates and subsequent separation of these concentrates into four (4) separate products.
Although flotation has made profitable the bene-ficiation of many low grade ores both metallic and non-metallic, it is not always true that flotation will give the greatest economic retiirn. For instance, in many cases, cyanidation of gold ores either direct or as part of a composite method of treatment may be the answer to the question of, what treatment will give the greatest dollar value return on the mill investment ?
An ore sample was received at the 911MPEEquipment Laboratory of a character which would ordinarily respond to the counter-current decantation method of cyanidation for extracting gold. Samples of the Same ore gave results concurring with test work by others but this method was not recommended due to settling difficulties encountered.
Work was not stopped here, however. Eventually, a successful method for treating this ore was found by sacrificing a small loss in slime. The final flowsheet evolved with recoveries indicated which made profitable installation of a reasonable cost plant, overcoming the difficulty arising from the physical characteristics of the ore.
Change of reagents in a flotation circuit may give higher recovery, a better grade of concentrates or both. A Sub-A Unit Flotation Cell installed in the grinding circuit may permit an increase in tonnage milled, a decreased loss in slimes and a better overall recovery.
AMineral Jigs installed in the grinding circuit in cyanide mills have proved very successful in increasing recovery. It is always advisable to recover your mineral values as soon and as coarse as possible.
Typical flowsheets are shown for both metallics and non-metallics as well as industrial products, wastes, etc. De-inking of waste paper by flotation, for example, is coming into prominence with Flotation Cells as it is now possible to recover for the paper industry a useful and usable product on a much more attractive basis than in the past.
Your flowsheet should be designed without bottlenecks or weak links which present problems that can seriously effect operating efficiency. The old saying of one hours delay means no profit today is more true today than ever before due to higher operating costs. This adage emphasizes the importance of having your flowsheet designed efficiently and tailored for your specific operation, and the need for selecting standard reliable equipment designed to give you continuous service.
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.

Jig machines for mining is one of the common gravity separation equipment. The working principle is separating the materials with different densities in the vertical lifting medium. According to the separation medium, the structure of equipment, the movement and other aspects, the jig machine can be divided into several types. In this article, we will let you know about the different types of jig machines for mining and their application.
According to the structure, the jig machine can be divided into piston jig, diaphragm jig, air pulsating jig, movable sieve jig and so on. Among them, the piston jig is an old type, which is basically not in use.
Diaphragm Jig machine is driving by the eccentric connecting rod, CAM lever or hydraulic equipment. According to the installation position of the diaphragm, it can be divided into up-motion(side-motion) diaphragm jig, down-motion cone diaphragm jig, side-moving diaphragm jig, which is the most useful type for gravity separation plant.
Up-motion(side-motion) diaphragm jig is most the equipment for roughing and concentrating. It is wildly used in the separation of tungsten, tin, gold and other metal minerals with large density. The separation particle size is from 0.2mm to 18-12mm. The characteristics are high enrichment and large stroke coefficient. There is only one type of up-moving diaphragm jig of 300mmx450mm, with double jigging Chambers in series. After the material is sorted by the first chamber, it enters the second chamber, and the two compartments reciprocate alternately to separate the material in the chamber.
The diaphragm of down-motion cone diaphragm jig is between the jigging chamber cone and movable cone. It is common as the roughing equipment for minerals with practical size under 6mm. The advantages are energy-saving and easy to pull out large density product, while the disadvantages are loose bed and worse effect in recovering coarse minerals under a large practical size.
This kind of mining jig machine has a trapezoidal face. The configuration is flexible. It has a short feeding part and a wide tailing part, which is an advantage for recovering fine ores. It is suitable for sorting minerals and gangue minerals with large mineral density and uneven mineral distribution. Sometimes, it is applied as the concentrating equipment for hematite and limonite.
Air pulsation jig is also known as piston-free jig, which is characterized by air compression for sorting, according to different air chamber locations can be divided into sieve side air chamber (side drum) jig and air chamber jig under the screen. Air pulsation jig is mainly used as a coal sorting equipment.
It can be divided into mechanical sieve jig and manual sieve jig according to the driving system. Manual sieve jig has been basically eliminated. Mechanical sieve jigger through hydraulic or mechanical force to drive the sieve plate to do reciprocating motion, to make the sieve plate on the material loose purpose. The moving sieve jig is mainly used as coal preparation equipment in large coal preparation or high cold water shortage areas.
2. When the jigging chamber has a large area and the stroke coefficient is relatively small, if the hydrodynamic force is insufficient or uneven, the bed may be "consolidated", this problem should be considered at the beginning of the design;
3. If there is a large amount of heavy sand in the mineral, it will be more difficult for jigging, which may lead to a decrease in the jigging operation rate. Check whether the sieve bed layer has deposited multiple sands in time, if this phenomenon should be promptly stopped to remove the material accumulated on the sieve.
From this point of view, from the understanding of the type of jig to the actual application of jig need to consider a comprehensive consideration of various factors, here it is recommended that the mine owner carry out ore dressing test and design in advance, by the construction of concentrator equipment manufacturers with the qualification of customized equipment, equipment selection and application to reach the expected level.
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.
