摘要/Abstract

摘要： 云南河口铜矿石含Cu 0.59%、S 4.57%、Fe 26.98%，属伴生硫铁的低品位硫化铜矿石，铜、硫、铁在矿石中分别主要以黄铜矿、黄铁矿、磁铁矿形式存在，但有少部分黄铜矿与黄铁矿形成固熔体。采用铜硫混合浮选—铜硫分离浮选—浮选尾矿弱磁选工艺对该矿石进行综合回收铜、硫、铁的选矿试验，得到了铜品位为18.03%、铜回收率为93.07%的铜精矿，硫品位为52.02%、硫回收率为56.34%的硫精矿和铁品位为61.90%、铁回收率为27.38%的铁精矿，从而为该矿石的合理开发利用提供了技术依据。

Abstract: Hekou copper ore in Yunnan contains Cu grade of 0.59%, S grade of 4.57% and Fe grade of 26.98%.It belongs to the S-Fe associated low grade copper sulphide ore, among which Cu, S and Fe exist in the form of chalcopyrite, pyrite and magnetite respectively.But there are a small amount of chalcopyrite and pyrite formed solid solution.Comprehensive recovery tests of copper, sulfur and iron were conducted by the process of copper-sulfur bulk flotation, copper-sulfur separated flotation, and low intensity magnetic separation of flotation tailings.Then, copper concentrate with Cu grade of 18.03% and Cu recovery of 93.07%, sulfur concentrate with S grade of 52.02% and S recovery of 52.02%, and iron concentrate with Fe grade of 61.90% and Fe recovery of 27.38% were obtained separately.This provides a technical basis for development and utilization of the ore.

Key words: S-Fe associated low grade copper sulphide ore, Copper-sulfur bulk flotation, Copper-sulfur separated Flotation, Low intensity magnetic separation
