use of lime in gold processing

use of lime in gold processing

Lime is used extensively in the recovery of gold and silver Ores either runofmine 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
