摘要
青海省某矿区难选含金多金属矿石丰富 ,矿石中富含有 Co、Ni、Cu、Au、Ag、Pb、Zn、Mo、Bi等有用元素 ,应用单一浮选或直接浸出 ,精矿中钴、镍、铜和金品位达不到合理的技术经济指标。采用预处理—湿法浸出工艺技术 ,可使钴、镍、铜和金的浸出率均达到 90 %以上。
There is abundant polymetallic ores in Qinghai province.These ores contain some important valuable elements.But,when the single flotation flowsheet or direct leaching technology is adopted,the reasonable techno economic targets for grade of cobalt,nickel,copper and gold in concentrates can not achieved.However,over 90% extraction percentages of these metals were achieved when the oxidation pretreatment hydrometallurgical leaching technology developed by authors was adopted.
