Abstract
The Bureau of Mines devised a column flotation technique using either fine or coarse bubbles and compared it with conventional flotation on a Montana chromite ore. On deslimed ore, fine-bubble column flotation produced a 44.7% Cr2O3-grade rougher concentrate with 87% recovery, compared with 43.8% and 43.5% Cr2O3-grade rougher concentrates with 85% and 77% recovery for coarse-bubble column flotation and conventional flotation, respectively. On undeslimed ore, coarse-bubble and fine-bubble column flotation produced rougher concentrates containing approximately 41.5% Cr2O3 with 95% recovery, exceeding conventional flotation, which produced 35.6% Cr2O3-grade concentrates with 87% recovery.
