摘要
综述了黄铜矿微生物浸出钝化作用和消除方法的研究现状和发展趋势,认为黄铜矿生物浸出的钝化作用主要有黄钾铁矾、硫及其多聚物、金属缺陷型硫化物和它们协同作用等。要提高黄铜矿生物浸出效果,必须削弱和消除钝化作用,主要的方法有物理法、化学法、生物法和复合法。但4种方法都还不成熟,要工业化应用,还需要大量的研究工作,同时提出从组合矿物对黄铜矿生物浸出钝化的影响开展研究工作,也许能取得突破性进展。
The phases that form during chalcopyrite dissolution could lead to hindering of the mineral＇s complete dissolution. This has most commonly been referred to as ＂passivation＂ of the chalcopyrite. Four surface phases such as jarosite, elemental sulphur allotropes, metal-deficient sulphides and their mixture might be responsible for hindered chalcopyrite bi- oleaching were reviewed. The elimination ways consisted of physical method, chemical method, biological methods, and mixed method. Much work will be done to eliminate passivation layers of chalcopyrite bioleaching by four methods. The study on effect of associated minerals on chalcopyrite bioleaehing might find a solution.
