Flotation of Chromite Ore

Effect of Pulp pH on Flotation of Chromite. The effect of pH on flotation response was originally performed on Benbow-1 ore (16.3 percent Cr2O3). The ore was ground to 88 percent minus 65 mesh and deslimed at a 30-micrometer particle size. The chromite was floated in three rougher stages with a total of 0.6 pound Arosurf MG-83A per ton of ore.
