Mining and processing of graphite: Technological advances and environmental challenges

The mining and processing of graphite is a complex and delicate process involving multiple technical links and environmental challenges. As the global demand for graphite resources continues to grow, mining and processing technology is also improving, but at the same time, it also needs to face increasingly severe environmental problems.In terms of mining, with the progress of geological exploration technology, people can more accurately locate the location and scale of graphite deposits, and improve mining efficiency. At the same time, the application of mechanization, automation and other technologies has also reduced mining costs and improved production safety. However, the waste rock, waste water and other wastes generated in the mining process have caused a lot of pressure on the environment, and effective treatment measures need to be taken.In terms of processing, the purification, crushing, molding and other processes of graphite are also constantly optimized. The new purificat

Summary of the characteristics, distribution and purification process of scales graphite

The scale graphite is high -pressure metamorphic. After weathering, it is generally blue -gray, yellow -brown or gray -white. It is mostly produced in tingling rocks, sliced rocks, crystalline litter and silicon hacks. Symbiosis is complicated, mainly consisting of sheet -like crystalline carbon, accompanied by long -stones, Yingshi, Black Cloud Mother, Pymaline Mine, Magnetic Yellow Elephant Mine, Golden Stone and other miscellaneous minerals. The graphite in the ore is a chip -like or blade -shaped, and the black or steel gray is mainly existing between the long stones, the time, the transparency of the pyroxyl, and the permeability of the glitter. It has obvious directional arrangement and consistent with the layer. Scales graphite is mostly natural crystal graphite with a layered structure and looks like fish scales. It belongs to the hexagonal crystal system. The crystalline state is good, the particle size is 0.05 ~ 1.5 microns, the thickness of the thin piece is 0.02 ~ 0.05 mm,

Antioxidant treatment method for battery specific graphite

The antioxidant treatment process of battery specific graphite includes material preparation, weighing, impregnation solution preparation, impregnation electrode treatment, and drying treatment. After graphite electrode treatment, it can be processed into various specifications of graphite electrode products. The treated graphite electrode is the same as the untreated graphite electrode. Compared with graphite electrodes, it has the characteristics of smooth surface and good conductivity. The mechanical design strength can be increased by 50-60%, the porosity gradually decreases by 10-15%, and the electrode material consumption can be reduced by 20-25%. Electrode consumption can be reduced by 20-25%.The antioxidant treatment of battery specific graphite has the following properties:(1) Preparation material weighing: Weigh the graphite electrode and provide qualified materials to be processed;(2) Preparation and heating of impregnation solution: The composition of impregnation solution

Graphite melting point

Graphite is a kind of homogenous alien in element carbon. Each carbon atom is connected to the other three carbon atoms (multiple hexagonal sixtures with honeycomb -shaped hexagonal) with covalent bonds to form covalent molecules. [1] Because each carbon atom will release an electron, those electrons can move freely, so graphite is a conductive body. Graphite is one of the softest minerals, and its purpose includes a pencil core and lubricant. Carbon is a non -metal element that is located in the second cycle IVA family located in the element cycle table. Latin is Carbonium, which means "coal, charcoal".The melting point of diamond is 3823K, and the melting point of graphite is 3773K. Graphite melting points are lower than diamonds. The melting point of graphite and diamond cannot be considered simply from the aspects of the key energy. If the number of broken keys during melting is ignored, the data obtained is not desirable

How to extract high -carbon graphite

The high -carbon graphite extraction method and the flotation method is low in the purity of minerals and the loss of reagents. This is the advantage of purifying high -carbon graphite. However, the application of floating and purifying graphite can only make the graphics of graphite unlimited improvement. For sheet -shaped graphite, not only can not solve its complete monomer, but it is not conducive to maintaining large hungusgogi. High carbon graphite must be chemically purified for graphite.(1) Pure method of high carbon alkali acidic acid. The carbon content purified by alkaline is more than 99%of the carbon content, which has the characteristics of less one -time investment, high product grade, and strong process adaptability. It also has a strong generality. The purity of non-metal minerals can use the advantages of alkali-acid method, and the alkali-acid method is the most commonly used method in my country today.(2) High -carbon graphite chloride and roasting method.

Types and uses of carbon solid raw materials

Carbon graphite material is a granular structure material made from various raw materials with different particle sizes, through the addition of binders, kneading, forming, roasting, and graphitization. Therefore, the performance of materials is not only related to the particle size, type and dosage of binders, as well as process control and operation during the production process, but also to the type and performance of the raw materials themselves.There are many solid raw materials used in the production of carbon graphite materials, such as ordinary petroleum coke, needle shaped petroleum coke, asphalt coke, artificial graphite, natural graphite, carbon black, anthracite, metallurgical coke, charcoal, sugar charcoal, bone charcoal, and so on; For electrochar products, there are also metal powders such as copper, silver, tin, lead, and artificial resins; For mechanical carbon and furnace lining materials, as well as silicon carbide, carbon dioxide, and patterned clay; For carbon fib
