In this process aggregation of raw graphite occurs to form individual particles along with creation of fine oil droplets and both collection of graphite particles and aggregates can be done [131]. As expected in the flushing process impurities move to the watery stage and the fine graphite cleans move from the water to oil [ 132 ].

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. …
