| 摘 要： | 针对湖北宜化殷家坪低品位难选硅镁质磷矿，采用阴离子捕收剂MG-7反浮选脱镁—沉降脱泥—阳离子捕收剂T609反浮选脱硅工艺. 在脱硅之前预先脱泥，同时消泡剂TOP和捕收剂T-609搭配使用，解决了阳离子反浮选脱硅过程中泡沫过稳定的难题. 获得品位为33.04%，回收率为69.50%的浮选精矿. 将分离的矿泥并入精矿，混合后精矿品位为30.56%，回收率为78.68%. 相比于传统的正浮选工艺，此工艺不需加温有效地降低了选矿的成本.

| Abstract: | A low grade phosphate ore with high silicon and magnesium in Hubei was processed by a double reverse flotation with anionic collector MG-7 removing magnesium，sedimentation desliming and the cationic collector T609 removing silicon. The problem of over-stable foam in cationic reverse flotation process can be effectively solved by desliming before desilication，and combining collector T-609 with defoaming agent TOP. The grade of P2O5 achieves 33.04%，and the recovery is 69.50%. When combined slime with concentrate，the concentrate grade is 30.56% and the recovery is 78.68%. Compared with the traditional flotation process，this new technology without heating reduces the production cost2 |
