摘要:

某砷硫铅质金矿中金的品位为17~18g/T,砷的质量分数为20.1%~20.5%范围,硫的质量分数为18.46%,铅的质量分数为3.05%等以及其他的元素干扰使金的氰化浸出率为5%~10%范围内。矿样经过氧化12~15h后,在防膜剂和活化剂存在下,金的氰化浸出率可达80%~85%范围。二次氰化浸出后,可使金的氰化浸出率达90%以上,能获得较好的经济效益。

关键词: 砷硫铅金矿, 氰化浸出, 防膜剂, 活化剂

Abstract:

The content of gold in the gold ore containing arsenic,sulphur and lead is about 17 to 18g/T,and the gold ore contains 20.1~20.5(mass fraction)arsenic,18.46% sulphur and 3.05% lead,which restricts the cyanide leaching rate also disturbed by other elements within 5%~10%.However,the gold leaching rate reaches 80%-85% with the existence of anti-film agent and activator after the ore is oxidized for 12~15 h.Moreover,the gold leaching rate reaches beyond 90% after cyanide leaching for the second time,which can benefit a lot.

Key words: gold ore containing arsenic,sulphur and lead, cyanide leaching, anti-film agent, activator
