黄铜矿 (ＣｕＦｅＳ2 )是工业上生产铜的主要资源。Ｎ .Ｂ .Ｄｅｖｉ等人研究了在二氧化锰存在下黄铜矿在盐酸介质中的氧化特点。研究结果表明 :1 .在ＨＣｌ介质中 ,黄铜矿单独存在时不能溶解 ,而有ＭｎＯ2 存在时则可有效地溶解。2 .ＣｕＦｅＳ2 的氧化可通过三条途径实现 :(
Chalcopyrite (CuFeS2) is a major source of industrial production of copper. N. B. Devi et al. Studied the oxidation of chalcopyrite in hydrochloric acid in the presence of manganese dioxide. The results show that: 1. In the HCl medium, the chalcopyrite can not be dissolved alone, but can be effectively dissolved in the presence of MnO2. 2. CuFeS2 oxidation can be achieved by three ways:
