Flotation of Chromite Ore

Amine flotation research was also performed on an ore sample from the Mouat mine. The ore sample contained 23.4 percent Cr2O3. It was ground to 100 percent minus 65 mesh, deslimed at the 20-micrometer particle size, and floated in a three-stage rougher using a total of 0.4 pound of Armac C per ton of ore.

Flotation Conditioning

In flotation dry-crushed ore gives poor separations, and wet grinding is essential to secure effective wetting and sinking of the unwanted gangue particles. After passing through the grinding section, the resulting pulp must conform to two conditions. Firstly, the particles of ore must be as nearly as possible of the size required for flotation.
