Study on Recovery of Molybdenum from High-sulphate Ammonium Molybdate Solution by Extraction AITranslate
Abstract AITranslate
Extraction method was employed to recover molybdenum from the high-sulphate ammonium molybdate solution obtained by the pressurized oxidized ammonia leaching-purification process of molybdenum concentrate.The effects of 2-octanol concentration, acid dosage, O/A phase ratio and oscillation time on Mo extraction were investigated.The results show that the optimal extraction conditions are 2-octanol volume fraction of 15%,1∶1 sulfuric acid dosage of 10% feed liquid volume, O/A phase ratio of 1.2/1 and oscillation time of 5 min.Through single-stage extraction, washing and single-stage stripping, the average Mo extraction rate reaches 99.61%,the Mo stripping rate is close to 100%,and the average Mo and SO42-contents are 161.99 g/L and 18 g/L,respectively, realizing the efficient recovery of molybdenum.
