Selective Flotation an overview ScienceDirect Topics

In graphite ore, sericite is one of the main gangue minerals, and thus it is a major impurity in graphite flotation concentrate [128]. The study of entrainment property of sericite in amorphous graphite flotation revealed that the entrainment of sericite leads to the poor flotation selectivity of commercial microcrystalline graphite ore [95

Flotation studies on low grade graphite ore from eastern

May 01, 2015· In froth flotation, graphite ore is treated with hydrocarbon oil to enhance the hydrophobicity and in turn recovery. The effect of diesel and pine oil on flotation performance was discussed earlier. In the case of lean and finely disseminated ores, fine grinding is essential to liberate values from gangue minerals,.

Beneficiation Study on Low-Grade Graphite Ore of Shounter

concentration of low grade graphite ore is froth flotation because of its natural hydrophobicity [4, 10, 11]. Along with froth flotation, chemical treatment like acid leaching is also considered to be essential since, it is difficult to produce high purity graphite only by mechanical processing techniques [12].

Graphite (C) Classifications, Properties & Applications

Sep 10, 2002· After graphite is mined, it usually requires a considerable amount of mineral processing like froth flotation to concentrate the graphite. Natural graphite is an excellent conductor of heat and electricity, stable over a broad range of temperatures, and a highly refractory material with a high melting point of 3650 °C.

Flotation Of Graphite

Flotation Of Graphite. The flotation method is a relatively common method for purifying minerals Since the graphite surface is not easily wetted by water it has good floatability and is easily separated from impurity minerals The flotation of graphite ore is generally carried out by positive flotation followed by reverse flotation of the flotation concentrate.
