2002-9-1  By incorporating the middlings fraction as product, the mass reduction would increase to 43.7%, while losses of valuable 2.1 mm product reduce to 18%. A significant mass reduction is therefore possible by treating coarse (−3+2 mm) diamond concentrate. However, a possible loss of 18% of the fine valuable material could occur. 3.2.2.

Flotation Machines Mineral Processing Machine ...

2 天前  Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
