Graphite ore processing brief introduction:
China's graphite mines mainly include: flake graphite and microcrystalline graphite. At present, the main beneficiation method is the use of flotation method for beneficiation, the flotation process and the required equipment can be simply used to demonstrate:
Graphite has good buoyancy, and it is currently used for flotation. The commonly used flotation agents are kerosene, No. 2 oil, water glass, lime, etc. Due to the large degree of inlaying of graphite, the grinding fineness is coarse, usually 100 mesh accounts for 45-60%.
Flake graphite mostly adopts the flotation process of squeezing and re-grinding of coarse-tipped mines, that is, rough grinding and rough-sorting are first performed to obtain low-grade tip minerals (grades of 40-50%) mainly composed of contiguous bodies, and then low-grade fines are produced. The mine is reground and re-elected to the final concentrate. The re-grinding time is 3-7 times, generally 3-4 times. The final concentrate grade is generally between 85-89%. It is used to inhibit symbiotic minerals such as pyrite and mica. Can add lime, paste tip, water glass and other agents.
Graphite mineral processing equipment
It mainly includes jaw crusher, ball mill, grading machine, magnetic separator, mixing tank, flotation machine, high gradient magnetic separator, etc.
Jaw crusher: jaw crusher commonly known as the broken, also known as tiger mouth. The jaw crusher consists of moving jaws and static jaws, which simulates the animal's two jaw movements and completes the crusher for material crushing operations. Widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries in a variety of ore and large pieces of material in the medium-sized crushing.
Ball mill: The ball mill is the key equipment for crushing after the material is broken. Ball mills are widely used in cement, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal beneficiation and glass-ceramic industries, and dry or wet grinding of various ores and other abrasive materials. It is widely used in various sectors of the national economy such as mineral processing, construction and chemical industry.
Flotation machines: Flotation machines are mainly used in non-ferrous metals (copper, lead, zinc, gold, silver, platinum and tungsten, molybdenum, tantalum, lithium, tantalum, uranium, etc.), ferrous metals (iron ore, titanium ore, manganese ore, Vanadium ore, etc., are mostly processed by magnetic separation, and the beneficiation of non-metallic mine resources, that is, flotation beneficiation processes, in addition, can also be used in the flotation separation of some special substances such as electrolytic aluminum.
1. The equipment configuration is high-end, the layout is compact and reasonable, the total floor space is very small, and the civil construction investment is greatly saved.
2. the degree of automation is relatively high, the computer can be remotely controlled, human, material and other aspects of investment costs are lower.
3. the operation is more safe and stable, the failure rate is very low, can save a lot of maintenance costs, no dust and noise, will not cause damage to the environment.
4. The grade of concentrate obtained has been increased by 10%, greatly increasing the industrial value of graphite mineral materials, and the comprehensive recycling rate has been significantly improved.
