摘要
东坑金矿中自然金呈粗细不均匀嵌布．采用浮选加尾矿重选，可得金租精矿品位２０．７７ｇ／ｔＡｕ，回收率９０．４９％；重选加尾矿氰化，最终浸渣含０．１０／ｔＡｕ，金的总回收率９８．３３％；全泥氰化，浸出率９４．８１％，贵液进入锌置换作业，置换率９７％～９８％，改用炭浆法提金也获良好指标．
The native gold in Dongkeng Gold Mine assumes inhomogeneous dissemination in particle sizes.When flotation plus tailings gravity separation is applied, the results that the gold grade of the gold rough concentrate is 20. 77g/t An and.the recovery is 90.49%can be obtained.If gravity separation plus tailings cyanidation is applied, the final leach residue will contain 0.1g/t An and the total recovery of gold can reach 98.33%.By total slime cyanidation, the gold leaching rate is 94.81%;the valuable liquid will enter the Zn replacement operation and the replacement rate can reach 97%～98%.When the gold is extracted by means of carbon-in-pulp (CIP)process,good results can also be obtained.
