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 method
The 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. Sealing must be properly handled on the tail gas, so it is limited to its promotion and application to a certain extent.
(2) Purification of alkali acidic acid
The carbon content after the purity method of alkaline acid method can reach more than 99%, which has the characteristics of less one -time investment, high product quality, and strong process adaptability. The purity of metal ore can adopt the advantages of alkaline acid method). The alkaline acid method is a wider method for applications in my country today. The disadvantage is that it has large energy consumption, long response time, large graphite loss, and serious wastewater pollution.
