Graphite ore flotation processing flow chart

The flotation of graphite ore is generally carried out by positive flotation followed by reverse flotation of the flotation concentrate. A higher grade graphite concentrate can be obtained by flotation. Flotation graphite concentrate grades can usually reach 80% to 90%, using multi-stage grinding; the purity can reach 98%.
