Cuprite (CU20, copper 88.8%, density 5.8~6.2g/cm3, hardness 3.5~4). Flotation is the main separation method of modern copper oxide ore. It can divide into direct flotation and sulfide flotation according to the different properties of copper oxide ore. Copper sulfide ore mainly includes single and polymetallic copper sulfide ore.

GOLD RECOVERY BY FLOTATION. A test on a sample, crushed to pass a screen of 120 holes per linear inch, containing $37 gold and 4.8% copper, gave a recovery by flotation alone of 90% of the gold and 98.5% of the copper, but left $8 gold in the tailing. The concentrate carried 44% insoluble matter, which could be reduced by re-treatment.

The flotation process, which was responsible for the almost complete change in equipment, has also undergone marked changes since its introduction in large-capacity concentrators. Flotation, when first introduced between 1913 and 1916, was used primarily to reduce losses of copper in the fine tailings of gravity plants.
