宜昌中品位胶磷矿双反浮选试验研究

Research on two-stage reverse flotation test of middle-grade phosphate ores from Yichang Mining Area

对湖北宜昌镁硅含量较高的难选胶磷矿采用阴离子捕收剂反浮镁、阳离子捕收剂反浮硅的双反浮选工艺进行了选别试验,获得了较好的浮选指标。

Tests were conducted on the double-reverse flotation process using anion collector for flotation of magnesium and cation collector for flotation ofsilicon for separating phosphate rocks with high contents of magnesium and silicon and difficulty of being beneficiated with the desirable floatation indices obtained.
