厅宫铜矿难采低品位资源综合回收技术方案研究

西藏尼木县厅宫铜矿区氧化铜矿保有储量为61469780.7t,铜金属含量237181t,平均品位0.4628%。该矿区位于高海拔,山高坡陡,地势险峻,矿体分散,而且矿区中部有彭岗玛曲横贯而过,属于典型的难采低品位铜矿资源。文章针对该矿资源特点以及矿区建设外部条件,提出了采用堆浸—萃取—电积工艺,并进行了技术论证和经济分析。

Research on the Integrated Recovery Technology of Difficult Mining Low-grade Resource of Tinggong Copper Mine

In Tinggong copper mine of Nimu County, Tibet, oxide copper reserves are 61 469 780.7 tons, including copper metal 23 7181 tons, the average grade is 0.4 628 percent.This mine area is located at high altitude, with high mountains, steep terrain and scattered orebodies, moreover there are ores in central Penggang Maqu, which is low-grade copper resources and typically difficult to mine.According to the resources features and external conditions of Tinggong copper mine, heap leaching-extraction-electrodepositing technology is presented, and technical feasibility studies and economic analysis are done.
