对于某矿山浮选产出的铜金精矿，由于铜的影响及黄铜矿和黄铁矿等物质对金的包裹作用的影响，直接氰化浸出的金、铜回收率均很低，虽然采用火法工艺处理该类精矿可较好地解决金、铜回收率低的问题，但是存在环境污染等问题。重点对铜金精矿超细磨-热压浸出-萃取-电积提取铜、浸出渣硫代硫酸钠法提取金和煤油溶解回收单质硫的综合回收工艺进行了研究，结果表明应用该综合回收工艺之后，铜、金和单质硫的回收率分别达到95%、98%和99%，具有有价金属综合回收率高且对环境污染小的优点。

As the impact of the copper and the chalcopyrite and pyrite inclusions of gold,the copper-gold concentrate which is the output of a mining flotation was cyanided directly,and the recoveries of gold and copper were very low.Although the problem can be solved by using pyrometallurgical processes dealing with the concentrates,but that cause environmental pollution and other issues.The copper-gold concentrate comprehensive recovery process was studied,which extracting copper from copper-gold concentrate using the process of ultra-fine grinding-hot leaching-extraction-electrowinning,extracting gold from leach residue using sodium thiosulfate method,recovering elemental sulfur using kerosene dissolved.The process has a lot of advantages,such as high recovery of valuable metals and environment friendly.The recovery rate of copper,gold and sulfur are up to 95%, 98%and 99%respectively.
