本文通过铜绿山铜铁矿尾矿的综合利用及物质组分研究 ,以期对尾矿的综合利用及尾矿污染的防治与对策提供可靠的理论及实验依据。物质组分研究结果表明 ,该尾矿的主要铜矿物为黄铁矿和戴氏赤铜矿等 ;主要的铁矿物是赤铁矿、褐铁矿及磁铁矿等 ;另外含有极少量的闪锌矿等。尾矿中铜和铁的含量分别是 0 .65%和 2 5.61 % ,即全部尾矿中蕴藏有 7.2万 t铜和 30 0万 t铁 ,这相当于一座中型铜矿和一座中型铁矿 ,同时尾矿中还蕴藏有相当的 Au、Ag、Mn、Co、Re等有益元素 ,综合利用前景十分广阔。
In this paper, Tonglushan copper and copper mine tailings comprehensive utilization and the study of the material composition, with a view to the comprehensive utilization of tailings and tailings pollution prevention and countermeasures to provide a reliable theoretical and experimental basis. The results of material composition show that the main copper minerals of the tailings are pyrite and deuterochronite; the main iron minerals are hematite, limonite and magnetite; in addition, a very small amount Sphalerite and so on. The contents of copper and iron in the tailings are 0.65% and 2. 5.61% respectively, that is, all the tailings contain 72,000 tons of copper and 3.0 million tons of iron, equivalent to a medium-sized copper mine and a medium-sized iron ore, At the same time tailings also contain a considerable amount of Au, Ag, Mn, Co, Re and other beneficial elements, the comprehensive utilization of a very broad prospect.
