织金中低品位磷矿石反浮选工艺的探索

Exploration on the Reverse Flotation Technology of Zhijin Median or Low Grade Phosphate Rocks

通过分析贵州织金县某地区磷矿石化学成分,对原矿进行了一系列的反浮选工艺试验研究。结果表明:原矿中P2O5含量可从22.60%提高到30.31%,MgO含量从6.51%降至1.41%,P2O5回收率88.17%,达到选矿指标要求。

Phosphate ore of Zhijin phosphate deposit was studied by adopting the reverse flotation technology experiment according to the natures of phosphate ore. The results show that the concentrate of 30.31%, MgO 1.41% had been obtained from phosphate ore containing P2O5 22.6 %, MgO 6.51% respectively. A recovery of 88.17% P2O5 could be reached.
