摘要
鄂东南计有铁、铜、钨铜钼、金和铅锌五类金属矿山,已堆积尾矿过亿m3。样品的化学-光谱分析、砂光片及轻砂鉴定表明,尾矿乃原矿经人工机械破碎-磨矿的碎屑堆积物。其中,可回收的主要有用组分是:TFe(铁矿砂)、Cu、Au、WO3(白钨矿)和S,以及铅锌矿山尾矿中的Pb、Zn和Ag。这些组分主要赋存在铁氧化物类和铜铁硫化物类矿物中。此外,部分尾矿库中的尾矿可作非金属建筑材料。最终尾矿是采矿时的充填料。
In southeastern Hubei province,there are five types of metal mines,including iron,copper,tungsten-copper-molybdenum,gold and lead-zinc,which accumulate up to more than a hundred million cubic meters.According to spectrochemical analysis,assay of sanding lapping and light sand of samples,tailings is clastic deposits,made from raw ore crushed and ground by artificial controlled machinery.The main available components which can be recycled are as follows： TFe,Cu,Au,WO3 and S,as well as Pb,Zn and Ag in tailings of lead-zinc mine,these components exist in minerals of iron oxide type and copper-iron sulfide type.In addition,some tailings may make as nonmetallic building materials,and at last tailings are stuffing materials when mining.
