Extraction of Tungsten and Molybdenum from Scheelite Chemical Beneficiation Acidic Leachate AITranslate
Abstract AITranslate
Tungsten and molybdenum were extracted from scheelite chemical beneficiation acidic leachate with the organic system of 15 % N235 ＋ 10 %TBP＋75 % sulfonated kerosene. The saturated loading capacity for Mo and WO3 of the organic system reaches 90.73 g/L,and the extracted complex ratio between N235 and Mo and WOa is 0. 886. Mo and W are extracted mainly in the form of MoO2Cln（n-2）- and H2WO4 ,respectively, Fe in the form of complex anion and P in the form of H3 PO4. The single stage extraction rates of Mo,WO3,Fe and P are 76.3%,94.8%,99.1% and 7.5% ,respectively. The loaded organic phase was eluted using dilute HC1 solution （pH=2）. The removal rates of Fe and P reach 99.6% and 77% ,respectively. The single stage stripping rates of Mo and WOa are 88.35% and 66.52% ,respectively by using 2 mol/L NaOH solution.
