| 摘 要： | 通常认为Fe3+离子是溶浸黄铜矿的有效氧化剂,Fe2+仅仅是Fe3+离子的供给源。但是有试验研究表明,对某些性质的黄铜矿而言,Fe2+离子比Fe3+离子具有更强的溶浸作用。本文对比了Fe2+与Fe3+离子浸出云南大红山黄铜矿的差异,详细研究了pH值、溶氧和Fe2+离子浓度等因素对低电位化学浸出的影响,并根据试验研究结果,系统总结了低电位化学浸出云南大红山黄铜矿的规律。

| Abstract: | It is generally accepted that ferric ions as an oxidant are effective for leaching chalcopyrite but ferrous ions contribute to the leaching only as a source of ferric ions.However,there are some research results which suggest that ferrous ions contribute to the copper extraction from chalcopyrite.In this paper,the authors have compared the differentia between Fe2 and Fe3 ,and the effects of some factors,such as pH,dissolved oxygen and ferrous ions concentration on chemical leaching of chalcopyrite are analyzed. |
