The metallurgical process DRDGOLD

One stream, the flotation concentrate, contains the sulphides which are enriched with gold while the second stream, the flotation tails, is made up of lower-grade siliceous material. This stream is treated by the conventional CIL process, which is the treatment process that has been used for the past 30 years with an extraction efficiency of 39% to 40%.

Lime in Flotation and Recovery Processes Graymont

Lime is used extensively in the recovery of gold and silver. Ores, either run-of-mine, milled, autoclaved or roasted, are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution, keeping it in the liquid phase and preventing the formation of hydrogen cyanide gas and its loss into the atmosphere.
