提高山东某金矿选矿回收率的试验研究

Experimental research on improving flotation recovery rate in a gold mine in Shandong

对以黄铁矿为主要载金矿物的山东某金矿矿石进行了试验研究。采用高效捕收剂Y-89,取得了金精矿品位62.76g/、t回收率93.83%的试验指标,成功地解决了该金矿金回收率难于提高的问题。

The ore flotation＇test in a gold mine in Shandong was performed, where gold is mainly carried by pyrite. With collectors Y - 89, the gold concentrate grade is 62.76g/t and the recovery rate is 93.83%. The test successfully solved the problem of difficulty in improving recovery rate of the gold ore.
