Graphite: A Multifunctional Additive for Paint and Coatings

Oct 01, 2003· Flake graphite is removed from its enclosing "ore" rock by crushing the rock and separating the graphite flakes by froth flotation. "Run-of-mine" flake graphite is available in purities between 80 and 98 percent carbon. Most processors are also capable of supplying 99% carbon flake graphite through various additional purification methods.
