摘要
本文介绍了镇源金矿东瓜林矿段混合矿石的提金工艺。该矿石由于金嵌布粒度极细，氧化程度高，矿石中含有少量硫化物包裹金及对氰化浸出影响极大的碳质物，采用单一浮选或氰化浸出工艺均难以获得好的选冶指标。试验采用浮选—浮选尾矿氰化浸出（树脂浸出法）的原则流程，获得了金总回收率８５．
The technology of extracting gold from mixed ores of Donggualing Section of Zhenyuan Gold Mine was introduced in the article. Due to the finegrained dissemination of gold,high oxidation of pyrite,and gold trapped by the sulphide and the carbonaceous matter which affect the efficiency of gold leaching,the single flowsheet of flotation or cyanidation leaching was not satisfied to get a high recovery index,therefore,a combined flowsheet, flotationcyanidation leaching with resin adsorption,has been used.The total recovery is high to 85.46%.
