过氧化物辅助浸出(PAL)的氰化提金新工艺

Cyainde leaching of gold reinforced by peroxide assistant leaching

介绍世界黄金工业中近年发展起来的以过氧化氢、过氧化钙等为氧化剂的过氧化物辅助浸出(PAL)法氰化提金新工艺.该工艺能加速浸出、提高金回收率、降低成本,且可适用于难处理矿石.

This paper introduces the world advance in cyanide leaching reinforced by peroxide assistant leaching, in which the hydrogen peroxide or calcium peroxide is used as oxidant.By this method, the gold leaching can be accelerated, gold recovery improved, operation cost reduced and refractory ores well-treated.
