Graphite – Green Power Energies
Due to its limited purity and flake size amorphous graphite is mainly used in standard commodities (lubricants, brake linings, refractories, steelmaking where higher ash contents are acceptable) and is the lowest priced graphite. Major deposits of amorphous graphite are found in China, Mexico; there are also deposits in the US and in Europe.
Graphite (Natural) - USGS
During 2020, China was the world's leading graphite producer, producing an estimated 62% of total world output. Approximately 40% of production in China was amorphous graphite and about 60% was flake. China produced some large flake graphite, but much of its flake graphite production is very small, in the +200-mesh range. China also
Natural Flake Graphite | Asbury Carbons
Graphite from Canada runs 90-97% carbon and graphite from China 90-96% carbon. Careful control of the floatation methodology can generally improve the purity but floatation cannot reduce the level of "intercalated" mineral matter. The size of the graphite flake is a very important commercial consideration.
