中国铜氧化矿石储量很少,且品位极低,仅有0.15%～0.3%。在2000年以前,我国在云南省的东川、易门、牟定、大姚和新疆拜城滴水沙岩铜氧化矿较多。近年来,在山西省中条山、秦岭北麓八一铜矿和河北的张家口、平泉县一带也有少量氧化矿。这些都是采用湿法冶炼(稀硫酸喷淋堆浸办法)然后萃取电解提取电铜,这种方法工艺简单、成本低,但提取产量只占我国铜总产量的0.28%～0.3%,我国北方没有大量推广和采用。
China’s copper ore reserves very little, and the grade is very low, only 0.15% to 0.3%. Before 2000, China’s Dongchuan, Yimen, Mouding, Dayao, and Baicheng drip sandstone in Yunnan Province had more copper oxide minerals. In recent years, a small amount of oxide ore has also been found in Zhongtiao Mountain in Shanxi Province, Bayi Copper Mine in the northern foot of Qinling Mountains and Zhangjiakou and Pingquan County in Hebei Province. These are the use of wet smelting (dilute sulfuric acid spray heap leaching method) and then extract the electrolytic copper extraction, this method is simple, low cost, but the extraction yield only accounts for 0.28% ~ 0.3% of China’s total copper output in northern China Not a lot of promotion and adoption.
