Introduction to Mineral Processing cpchem

Introduction to Mineral Processing. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.

Application of stirred mill to upgrading of graphite

ABSTRACTIt is difficult to obtain high grade concentrates for layered minerals, such as graphite, by mineral processing due to the existence of impurities between interlayers. Conventional grinding mills are inefficient in liberating the mineral layers. Upgrading a graphite concentrate by re grinding with a designed stirred mill is investigated in this paper.
