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.

16/04/2017· Generally, a residual strength of 0.05% CaO will indicate a suitable quantity of lime for an all-gold ore, and 0.1% for a silver or silver-gold ore. To obtain the amount of lime needed in terms of pure calcium oxide (CaO) the strength of the lime used for the test maybe ascertained closely by putting one gram in a litre of distilled water, and agitating in a bottle for 8 or 10 hours. The water ...

Ore processing – Waihi Gold

The slurry (1) of ground ore and lime moves into a series of six leach tanks (2) where a sodium cyanide solution is added. The tanks provide sufficient retention time to allow the gold and silver to be dissolved by the cyanide solution. Oxygen is added to assist in this process. The slurry then moves through a series of carbon adsorption tanks ...
