Graph

Floating method is a type with less energy consumption and reagent consumption and low cost in the conventional purification method of minerals. Real limited improvement. For scales graphite, multi -segment grinding ore cannot be completely unbuttoned, but it is not conducive to protecting large scales of graphite. Therefore, the use of flotal methods to further improve the graphite quality. High carbide graphite with more than 99%must be pure graphite with chemical methods.(1) chloride roasting methodThe low roasting temperature and smaller chlorine gas consumption of chloride roasting method have greatly reduced the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to the treatment of hydrofluoric acid method. Compared with the recovery rate of chloride and roasting method, because the chlorine gas is poisonous and has strong corrosiveness, it requires high requirements for equipment operations. It requires strict requirements. Seal
