Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

The value and application of large scales graphite are much larger than fine scale graphite, and once it is destroyed, it cannot be recovered. Large scales that protect graphite in graphite are issues that cannot be ignored during the mining process. Because graphite has good natural floating, the floating method can increase the graphics of graphite to 80%to 90%, or even about 95%. The biggest advantage of this method is one of the minimum energy consumption and reagent consumption in all purification schemes. However, the compounds of silicate minerals and potassium, calcium, sodium, magnesium, aluminum and other elements that are mixed in graphite scales and potassium, calcium, sodium, magnesium, aluminum, etc. Essence Therefore, the flotation method is only a primary means of graphite purification. If you want to obtain high carbon graphite with more than 99%of the carbon content, you must use other methods to purify.
