Graphite ore is mostly beneficiated using flotation separation techniques. The increasing demand for high grade graphite products with up to 99.99% carbon has resulted in the development of various approaches to remove impurities even to parts per million range.
Graphite , archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure. It occurs naturally in this form and is the most stable form of carbon under standard conditions. Under high pressures and temperatures it converts to diamond. Graphite is used in pencilsand lubricants. It is a good conductor of heat and electricity. Its high conductivity makes it useful in electroWikipedia · Text under CC BY SA license
Flotation reagents for graphite beneficiation process The commonly used collectors for flotation crystal graphite are kerosene, diesel oil, heavy oil, sulfonate, sulfate, phenol and carboxylate. The common foaming agents are 2 oil, 4 oil, pine oil, ether alcohol and Butyl ether oil, etc., the adjusting agent is lime and sodium carbonate, and the inhibitors are water glass and lime.
