| Abstract: | Molybdate was prepared from the dust of molybdenum concentrate roasting.The results show that the dust was leached for 3 hours at 80 ℃ with H2SO4 with the ratio of solid to liquid S/L=1/40.And then extracted by N235 with W/O= 2∶1,then organic phase was washed by 0.27 mol/L NH3·H2O at pH=1.5~2.0.The crystalline(NH4)3PO4(MoO3)12·4H2O with purity of 95.5% was obtained after filtration. |
