| 摘 要： | 四川清平烂泥沟矿段属典型的难选胶磷矿,多年的试验研究结果表明:单独选别低品位烂泥沟矿,指标不理想,P2O5回收率仅40%左右,且选矿成本过高,经济上不可行;将烂泥沟矿与其他矿段的高品位矿按一定比例混合入选,烂泥沟矿的选别回收率可达70%左右,且经济合理.

| Abstract: | The ore in Lannigou ore block of Qingping Phosphate Mine is a kind of refractory collphanite.The results of experimental investigation for many years showed that the indexes obtained from singly separating low grade Lannigou phosphate ore was unsatisfactory,its P2O5 recovery was 40 % approximately,and its beneficiation cost was excessive;whereas,the recovery of Lannigou phosphate ore could reach 70% approximately by separating the mixed Lannigou ore with high-grade ore in other ore block,and the process had... |
