铜硫混合矿的分选试验

Test for Saparating Flotation of Cu-S Mixed Ore

本文介绍在银山矿铜硫选矿指标不稳定、铜在硫精矿中损失严重的情况下．作者用6种不同矿区、不同比例的矿样做了两种流程、10组闭路选矿试验，其中以低品位综合矿试验为代表，与现场铜硫系统的生产进行了对比分析，为选矿工艺的改进和提高技术指标提供依据。

On the status of unstable Cu-S Ore-dressing Performanles and serious Cu-loss in S-concertrate of yinshang Pb-Zn mine,the writer nade test which had two flowsheet and ten closed-circuit ore-dressing by using six type samples of different ore ratio and mining avea,ore-dressing process and thechnical targets were contrasted between the test of low grade comprehensive ore and the productsite of Cu-S system,and then,improve basis was obtained in the paper.
