德兴铜矿酸性废水成因的研究

Study on the cause of formation of acidic waste water in Dexing Copper Mine

德兴铜矿废石场及露天采场每年都要产生大量的酸性废水 ,造成矿体附近河流的污染 ,究其成因 ,主要是由于黄铁矿的风化及雨水淋溶 ,并通过一系列的化学反应和微生物的作用而形成矿山酸性水。

Large amount of acidic waste water has been produced every year in dirt bing and open pit of Dexing Copper Mine, which has polluted the rivers around the orebody. The cause of formation of acidic waste water is mainly the weathering of pyrite and rainfall leaching, then a series of chemical reactions and microbiological actions.
