Phenomena in the froth phase of flotation — A review
Froth flotation was commercially introduced early in the 20th century. Now, almost 100 years later, it is the most important and widely used separating method for minerals.In its application to mineral flotation, the ore is first ground in water to a certain size to produce a suspension which is then subjected to vigorous mixing in a suitable vessel.

Processing Gold Ore by Flotation
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.
