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.

Silver Gold Recovery Flotation Process
Whichever reagent is used, it is better to introduce it into the cleaning circuit if possible, because any excess entering the machine through occasional faulty control is likely to cause a lower gold loss there than in the roughing circuit. The addition of copper sulphate up to 0.25 lb. per ton is sometimes found useful in speeding up flotation.
