Copper Gold Sulfide Ore – Flotation & Cyanidation Tests
Cyanidation of Copper Flotation Tailing. As described under "Flotation of Copper", concentrates containing percent of the copper, 62.7 percent of the gold, and 61.2 percent of the silver wore made by 1-stage cleaning. The cleaner tailing from this operation were then returned to the rougher tails. This combined material contained 0.15 ...

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.
