| 摘 要： | 利用新型捕收剂,采用单一反浮选的方法对沙特某低品位胶磷矿进行浮选试验,考察了磨矿细度、浮选时间、抑制剂和捕收剂用量对精矿P2O5品位和P2O5回收率的影响.结果表明,当原矿P2O5品位为19.60％,磨矿细度-0.074 mm占60％,浮选时间1.5 min,抑制剂用量11.09 kg/t,捕收剂用量1.0 kg/t时,可以获得P2O5品位32.23％、P2O5回收率86.86％的磷精矿. |

| Abstract: | A new collector was adopted in the flotation of Saudi low grade collophanite.The effects of grinding size,flotation time,dosages of collector and depressor on the grade and recovery of P2O5 in phosphate concentrate were investigated.The results of the experiments showed that a phosphate concentrate with P2O5 grade 32.23% and P2O5 recovery 86.86℅ could be achieved when the grade of raw ore was 19.60℅,grinding fineness of-0.074mm was 60℅,flotation time was 1.5min,dosages of depressor was 11.09 kg/t,and dosages of collector was 1.0 kg/t. |
| Keywords: | collophanite low grade flotation collector |
