Graphite Production Process - Nacional de Grafite

The ore is subjected to successive grinding and a mechanical process separating impurities from the graphite. The mechanical concentration aims for maximum recovery of the graphite present in the ore, preserving its physical features. Chemical Concentration. The chemical concentration is used to remove the remaining impurities in the previously ...
