The Bureau of Mines investigated column versus conventional flotation of chromtie and fluorite ores. Fine-bubble column flotation of deslimed chromite ore produced a 44.7% Cr2o3 rougher concentrate at 87.1% Recovery, whereas conventional flotation produced a 40.4% Cr2o3 concentrate at 85.4% Recovery. Column flotation of undeslimed chromite ore also produced results superior to those attained with conventional flotation. Column flotation of fluorite ore produced a 90.9% Caf2 rougher concentrate at 86.8% Recovery, compared with a 67% caf2 rougher concentrate at 90.4% Recovery produced by conventional flotation.
