晋宁磷矿脱泥-浮选工艺研究

摘要

The desliming and flotation process is an efficient way to grinding and flotation all for sorting the low grade phosphate ore with complex mineral symbiotic relationship and low recovery, which has characteristics of enhancing the utilization of process and equipment efficiently, and could reduce the energy and reagent consumption.Adopting this way to deal with the middle-low grade collophanite at Jinning, which could get concentrate of high quality: the content of P2O5 is 30.92％, the content of MgO and sesquioxide is 0.18％ nd 1.71％ respectively, and the recovery is 69.16％.%脱泥-浮选工艺是针对矿石品位下降,矿物共生关系复杂,回收率低等一系列问题提出来的一整套关于磨矿、浮选的有效解决手段,其特点是:合理利用流程设备,降低能耗及药耗.晋宁中低品位胶磷矿通过该工艺,试验获得P2O5 品位为30.92%,MgO为 0.18%,R2O3含量为1.73%5回收率为69.16%的优质磷精矿.
