浅析云锡老尾矿中锡石的工艺矿物学特征

本文通过对多个云锡尾矿区的物质组成分析,以及尾矿中锡矿石的组成、锡的赋存状态、锡石的晶体形态、锡石结晶粒度、锡石空间分布状态的综合分析,得出了老尾矿中锡石具有品位低、粒度细、共生关系复杂、泥化程度大等锡的工艺特性。

A Study of process mineralogy of cassiterite in old tailings of Yunnan Tin

On the basis of composition analyses of numerous old tailings in the possession of Yunnan Tin,a comprehensive analysis was performed in this paper from perspectives of cassiterite composition in tailings,occurrence state,crystal habit,grain size and spatial distribution.It is shown that cassiterite in old tailings incorporates a certain number of process features,i.e.low grade,fine grain,complex paragenetic relationship and high mudding degree,etc.
