常见金属硫化物电化学反应环境效应及其影响因素分析

金属硫化物矿物作为重要的金属矿产资源之一,在自然界广泛分布并易氧化(电化学反应)引起重金属离子和酸性矿山废水污染的环境效应。本文以黄铁矿和黄铜矿为例全面分析了金属硫化物矿物环境效应产生机制,以及影响金属硫化物矿物电化学反应的各种因素,指出了当前研究存在的不足。这对金属硫化物矿区环境污染的源头控制与修复具有重要的指导意义。

Environmental Effects of Electrochemical Interactions of Common Sulfide Minerals and Their Influence Factors

Metal sulfide minerals is one of the most important metallic mineral resources, they are widely distributed in nature and can easily be oxidized (electrochemical reaction) resulting in environmental effects, such as pollution of heavy metal ions and acid mine drainage. In this article, pyrite and chalcopyrite were selected as examples to comprehensive analysis of the generation mechanisms of metal sulfide minerals environmental effects, analysis the various factors affecting the electrochemical reactions of the metal sulfide minerals,simultaneously, and point out the defects and disadvantages appeared in current researches. This has important guiding significance for source control and remediation of environmental contamination in metal sulfide mine areas.
