【摘要】 通过分析贵州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23.01%提高到32.00%,MgO 含量从5.17%降至1.83%,P₂O₅回收率93.07%。同时,精矿中稀土和稀土钇的回收率均可达到90%以上,精矿的稀土品位最高为 REO 0.16%,稀土钇品位最高为 Y₂O₃ 0.054%。达到选矿指标要求。更多还原

【Abstract】 Phosphate ore tram some place of Guizhou province 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 32.00%,MgO 1.83% were obtained from phosphate ore containing P205 23.01%,MgO 5.17% respectively.A recovery of 93.07% P₂O₅ could be reached while in the rare-earth and rare earth concentrate yttrium recovery can be more than 90%,and Concentrates rare earth for the highest grade is REO 0.16%,the highest grade of Rare Earth Y is Y₂O₃ 0.054%.It could be reached the desire.更多还原
