摘要
针对紫金矿业集团黄金冶炼厂产出的含金废料 ,进行了焙烧湿法回收金的工艺研究。含金废料经焙烧去除炭质和有机物后 ,经氰化浸出、炭吸附回收金 ,金回收率可达 90 %以上。该工艺成本低 ,易实施 ,可获得良好的经济效益。
Recovery of gold from gold bearing waste material yielded in gold smelting plant of Zijin Mining Group by roasting hydrometallurgy are investigated.After organics and carbon being removeled,the material is leached with cyanide.Gold in leaching solution is adsorbed with activated carbon.Recovery of gold is more than 90%.The method has advantages of low cost,easy carrying out and good economic profit.
