Graphite Beneficiation Process

Solution to The Graphite Or ProblemA Graphite Froth Flotation FlowsheetGraphite Beneficiation ProcessMost low grade graphite ores are crystalline and respond very well to flotation treatment for graphite recovery. Where a fairly high percentage of the graphite in the comminuted ore is in the +100 mesh it is possible and sometimes desirable to screen out and recover the coarse fractions to market them as such. Coarse flake graphite generally commands a much higher price. On the other hand, where a maximum percentage of graphite in the concentrate is desired, the coarse fraction is recovered a...
