某锡铜铅锌多金属矿综合回收试验研究

Experimental research on comprehensive recovery of the Sn-Cu-Pb-Zn polymetallic ore

摘要: 该矿锡多金属矿含有锡、铜、铅、锌等多种有价金属矿物,综合利用价值高。试验主要在选锡前回收铜、铅、锌等伴生矿物,采用先铜铅部分混合浮选后锌浮选的工艺流程,闭路试验获得Cu品位23.49%,回收率85.98%的铜精矿;Pb品位56.22%,回收率80.77%的铅精矿;Zn品位47.09%,回收率87.21%的锌精矿。试验还获得了含S品位37.75%,回收率74.20%的硫精矿,同时尾矿中Sn的回收率为89.33%。达到了选锡前对铜、铅、锌等伴生矿物综合回收的目的。

Abstract: the Tin-polymetallic Ore had high value,containing many valuable metallic mineral such as tin,copper,lead,zinc.In order to callback the associated minerals such as copper,lead,zinc,the technological flow sheet of copper-Plead partial bulk flotation was adopted and finally the comprehensive recovery of copper,lead,zinc and sulfur was realized,among which the grade of copper,lead,zinc and sulfur was 23.49%,56.22%,47.09%,37.75% and their recovery was 85.98%,80.77%,87.21% and 74.20% respectively.At the same time,the associated tin in tailing was concentrated and its total recovery was 89.33%.reaching the aim of comprehensive recovery to associated minerals such as copper,lead,zinc.
