Solution to the Graphite Or Problem. Most 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.
