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 GravityFlotation process was employed
to classify Anning weathered phosphate ore into two
particle size fractions, and beneficiated separately
using the traditional directreverse 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.
