摘要
晋宁磷矿贫矿下Ⅱ级品下层矿属海相沉积型磷块岩。原矿含 P_2O_5 19.22%、MgO 0.55%、R_2O_3 6.46%,经过简单的工艺流程,在常温条件下,获得磷精矿含 P_2O_5 30.00%、MgO 0.32%,P_2O_3 3.47%,回收率83.06%的选别指标。为开发利用晋宁磷矿低品位矿石提供了依据。
Grade-Ⅱ underlayer ore from Jinning Phosphorus Mine is an oceanic sedimentary phosphate rock.Beneficiation index- cs of phosphorus concentrate with grade of P_2O_5 30.40%,MgO 0. 32%,R_2O_3 3.47% and recovery of P_2O_5 83.06% are obtained from the primary ore of P_2O_5 19.22%,MgO 0.55% and R_2O_36. 46% by simple flotation at normal temperature.
