摘要: 为了更好地综合利用中国高岭土公司的尾矿,对其中硫化矿物的存在状态进行了研究。结果表明:该尾矿中的主要有价元素为S,Zn,Pb,且Zn和Pb主要以硫化物的形式存在;主要有用矿物黄铁矿、闪锌矿和方铅矿中,黄铁矿单体程度较高,而闪锌矿和方铅矿的单体解离度较低。研究结果为该尾矿中有价元素的回收提供了工艺矿物学依据。

Abstract: To properly realize the comprehensive utilization of tailings from China Kaoling Clay Company,the occurrence situation of Sulphides are investigated.It is indicated that the main valuable elements in tailings are S,Zn,Pb,where Zn and P exist in sulfides.The main minerals are pyrite.There is a high single pyrite content in Sphalerite and Galena,both of which have a low liberation.Research results showed that the recovery of valuable elements from tailings provided a basis for the mineralogical analysis.
