摘要
对安宁风化矿采用"重-浮"分级方法,将原矿中体密度较小的多孔细粒级矿物浮出,再分别对"轻重"两部分产品采用正-反浮选工艺,均可得到品位P2O5≥30%、MgO≤0.3%的优质磷精矿.沉降试验表明,重组份浮选精矿的沉降速度是未分级前的3.12倍.
A new Gravity-Flotation process was employed to classify Anning weathered phosphate ore into two particle size fractions, and beneficiated separately using the traditional direct-reverse flotation process. A combined phosphate concentrate from the coarser and finer parts with grade P2O5≥30% and MgO≤0.3% could be obtained from this new process. Gravity sedimentation tests showed that the sedimentation rate of heavier concentrate was 3. 12 times greater than that of the tradition flotation concentrate.
