新疆砂岩型氧化铜矿资源丰富，主要分布在塔里木盆地周缘，是新疆的优势矿产资源。但其矿石类型较复杂，含碳酸盐和钙镁较高，亦有氯铜矿存在。针对新疆资源特征，项目研究并探讨了不同的浸出工艺条件，提出了基于低浓度氨堆浸的浸出-萃取-电积工艺，以达到成功开发新疆砂岩型氧化铜矿的目的。%Copper oxide ore distributes the margin of Tarim basin inXinjiang. Hydrometallurgy of copper has been developed rapidly in recently. It is possible to use the technology of heap leaching with low concentration ammonia to treat high alkali and low grade copper ore in Xinjiang. Because the problem of volatility of ammonia has been solved perfectly, so, this technology has the great advantage in economics and engineering.
