黄铁矿解抑活化机理研究现状及进展

Derepression and Activation of Pyrite:A Review

含有黄铁矿的多金属矿物浮选分离一般先采用石灰抑制黄铁矿以更好地选别其他有用金属矿物,随后再综合回收黄铁矿。为获得较好的回收指标,需对受抑制的黄铁矿进行解抑活化处理。在矿业工程领域,关于石灰抑制过的黄铁矿解抑活化机理等相关内容得到了广泛研究并取得一定进展。本文综合评述了影响黄铁矿可浮性的主要因素、不同种类活化剂对黄铁矿的活化机理及黄铁矿机械活化效应等相关研究进展,为今后黄铁矿资源高效加工理论与应用研究的进一步发展提供参考。

Lime depressing process is commonly used in the early stage of flotation separation for polymetallic minerals containing pyrite. This method performs better than other methods for separation methods. To obtain a better recovery, lime-depressed pyrite should be activated. In the field of ore beneficiation, the mechanism of activation of lime-depressed pyrite has been widely studied and some progress has been made. In this paper, the main factors affecting floatability of pyrite, the progress in research on the activation mechanisms of different activators, and the mechanical activating effect on pyrite were reviewed and discussed to provide a reference for the theoretical study and application of high-efficiency processing for pyrite resources.
