摘要: 本文针对湖北某铜矿回水对浮选影响展开研究，对回水水质进行了调查，发现回水为高碱硬水，pH达到12以上，Ca2+含量极高，还存在Mg2+、Cu2+、Fe3+等其他难免离子。基于回水水质调查结果，开展了pH对黄铜矿浮选行为影响，Ca2+对黄铜矿、黄铁矿浮选行为影响，Mg2+、Cu2+、Fe3+对黄铜矿、黄铁矿浮选行为影响等条件试验，最终依据条件试验结果，开展了石灰抑制黄铁矿作用机理研究，从而进一步印证了条件试验结论，完整地揭示了湖北某铜矿回水对浮选影响情况，对于指导该矿厂进行技术改造和生产实践具有重要意义。
Abstract: In this paper, the effect of backwater on flotation of a copper mine in Hubei was studied. The backwater quality was investigated, and it was found that the backwater was hard water with high alkali, pH accounts more than 12, and Ca2+ content was very high. There are also Mg2+, Cu2+, Fe3+ and other unavoidable ions. Based on the backwater quality survey results, the influence of pH on the flotation behavior of chalcopyrite, the influence of Ca2+ on the flotation behavior of chalcopyrite and pyrite, and the influence of Mg2+, Cu2+ and Fe3+ on the flotation behavior of chalcopyrite and pyrite were carried out. Finally, according to the condition test results, the mechanism of lime inhibition of pyrite was studied. Thus, the conclusion of the conditional test is further verified, and the influence of backwater on flotation of a copper mine in Hubei Province is completely revealed, which is of great significance to guide the technical transformation and production practice of the mine.
