转化法由低品铜矿制备活性氯化亚铜

Study on the preparation of cuprous chloride from low grade copper ore by catalysis conversion

研究了由低品位铜矿 (或含铜矿渣 )经转化法制取铜氨络合物 ,经蒸氨即制得纯净的氧化铜 ,再经过酸、溶、氯化还原等过程而制得氯化亚铜的工艺过程 .本方法具有铜转化利用率高 ,“三废”排放少 。

Active cuprous chloride was prepared from low grade copper ore (or contain copper slag).First, cuprammonia complex compound was prepared by catalysis conversion;second, pure copper oxide was obtained by evaporating ammonia; then, the product was gained by acidolysis and chlorization reduction. This method had advantages of high utilization ratio of coppor,few wastes and better quality of products.
