摘要
自然或人为采矿活动暴露的硫化物矿物的氧化作用 ,常产生一定范围的次生地球化学异常和严重的环境污染。在黄铁矿、方铅矿、闪锌矿、毒砂等硫化物矿物氧化过程中 ,S、Pb、Cd、As等有害元素将被有效释放而进入水体 ,并通过大气 -水 -土壤 -植物
The oxidation of common sulfide minerals exposed naturally,or more often by mining activities, often is responsible for the secondary geochemical anomalies and produces serious environmental problems During the oxidation of sulfide minerals such as pyrite, galena, sphalerite, and arsenopyrite, the harmful elements such as S, Pb, Cd, and As could be effectively released into the environment(air water soils plants animal)and risk human healthy
