摘要
对云南某中低品位风化胶磷矿采用脱泥—浮选工艺,在原矿P_2O_5品位为22.46%、R_2O_3质量分数为3.95%、磨矿细度为-200目质量分数占82.93%的条件下,获得了精矿P_2O_5品位为29.42%、R_2O_3质量分数为2.38%、精矿产率为60.45%、回收率为79.39%、精矿中R_2O_3的脱出率为63.31%的选矿指标。
The medium and low grade weathered collophanite in Yunnan was separated by desliming and flotation process.With the crude ore P_2O_5 22.46%,R_2O_3 3.95% and grinding fineness82.93% of-200 mesh,the phosphate concentrate with P_2O_5 29.42%,R_2O_3 2.38%,yield 60.45%,recovery rate 79.39%and R_2O_3 removal rate up to 63.31% was obtained.
