低品位含磷矿石的综合利用试验

摘要

The comprehensive recovery of apatite, diopside, biotite and iron ore in a low-grade phosphate ore was introduced.The experiments adopted low cost gravity-magnetic separation process flow and separated phosphate concentrate of 31％ P2O5 from crude ore with 3.44％ P2O5.At the same time, biotite of 31.06％ and pyroxene of 51.14％ were recovered, and iron concentrate with TFe 68.20％ was attained.The technical and economic index was better.%介绍某低品位磷矿中磷灰石、透辉石、黑云母、铁矿石的综合回收情况,试验采用低成本的重选-磁选联合工艺流程,从P2O5品位为3.44%的原矿中选得P2O5为31%的磷精矿,同时回收了矿物量分别为31.06%和51.14%的黑云母和辉石产品,并得到含TFe为68.20%的铁精矿,取得较好的技术经济指标.
