摘要
对贵州瓮福磷矿矿石试样进行了实验室开路磨矿和闭路磨矿的对比试验 ,结果表明 :采用开路磨矿 ,磷精矿P2 O5含量提高了 1.8%～ 3.0 % ,磷回收率提高了 1.59%～ 4 .4 8% ,MgO含量降低了 0 .35%～ 0 .57%
Comparison tests for laboratory open circuit grinding and closed circuit grinding were performed with ore samples from Wengfu Phosphate Mine, Guizhou. The results of the tests showed that when open circuit grinding was used, the content of phosphorus concentrate and the recovery of phosphate could be increased by 1.8% [similar to] 3.00% and 1.59% [similar to] 4.18% respectively and the MgO content be reduced by 0.35% [similar to] 0.57%.
