Lime in Flotation and Recovery Processes
Both Quicklime and Hydrated Lime are widely used in the flotation and hydrometallurgical processes to aid the recovery of valuable minerals and metals including gold, silver, copper, zinc, nickel and lead-bearing ores.
Lime is used extensively in the recovery of gold and silver. Run-of-mine, milled, autoclaved or roasted ores are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime is vital to maintain the correct pH to keep cyanide in solution keeping it in the liquid phase and preventing the formation of dangerous hydrogen cyanide gas and associated loss into the atmosphere.
There is nuance and skill involved in using lime to best effect and SHC's technical know-how can assist customers to define optimum lime slaking and mixing solutions to suit their needs.
