摘要：

某高砷金矿中金的品位为17g/t - 18g/t，砷的质量分数为20.15 % - 20.5%范围，硫的质量分数为18.46%，铅的质量分数为3.05%。金主要被砷化物及硫化物包裹不易氰化浸出。金矿直接焙烧后，金的氰化浸出率为56.17%，加入助剂焙烧后，金的氰化浸出率为81.48%以内。若在氰化反应体系中加入2 kg/t 增浸剂后，金的氰化浸出率为87%%-90%，金的氰化浸出速度得到提高。

Abstract:

The content of gold of certain gold ore containing high content of arsenic is 17g/t-l8g/t, and the gold ore contains 20.1％- 20.5％ (rnass fraction) arsenic, 18.46％ sulfur and 3.05％ lead, and gold is hardly cyanide leached mainly since parceled up by arsenide and sulphuret. The gold cyanide leaching rate is 56.17％ by direct roasting, but within 81.48％ with addition of auxiliary agent, then reaches as high as 87％- 90％ with addition of 2kg/t leaching agent and improves the velocity of cyanidation as well.

Key words: gold ore, masting, auxiliary agent, leaching agent
