improve graphite grade including physical, chemical and thermal methods 15. However, Because of nat-ural hydrophobicity of graphite, flotation is the most used technique for its beneficiation 15. In fact, a survey of literature indicates that graphite was the first mineral to be concentrated by flotation by Bessel Brothers in 1877 15.
Jun 01, 2020 The floatation method is to use the floatability of graphite to enrich and purify the graphite, which is mainly suitable for the natural flake graphite with good floatability.The final concentrate grade of graphite after flotation is usually about 90, sometimes 94-95.
grade are the key factors in determining value and price of a graphite product. For example, jumbo flake 48 mesh or large flake 80 mesh graphite grading better than 95 carbon is suitable for use in lithium batteries. Flotation is a common means of processing graphite but other approaches can be necessary, depending on the

Jun 05, 2019 Mineral Notes Graphite. 5 June, 2019. This article was written by Executive Consultant, Andrew Scogings. Graphite is an allotrope of carbon and is grey to black, opaque, very soft, has a low density and a metallic lustre. It is flexible and exhibits both non-metallic and metallic properties, making it suitable for diverse industrial applications.
With the development of expanded graphite and anode materials industry, there is much requirement on high purity graphite product. It is very hard to reach the grade above TGC 96 just by the stage grinding and flotation processing. To get higher grade above TGC96 or even above TGC 99.95, deep processing should be applied.
