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。
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 - 15h. Moreover, the gold leaching rate reaches beyond 90% after cyanide leaching for the second time, which can benefit a lot.
