How to Purify Graphite Ore?

Tapioca powder, acorn powder, sodium alginate, and polyacrylamide are used as flocculants to purify graphite ore. The selective flocculation purification method and equipment of graphite ore are relatively simple, and the cost is low, but the recovery rate of fixed carbon is low, only about 40%. 2. Graphite Ore Flotation.
