用粗钼酸制备钼酸铵工艺的研究
Research into preparation of ammonium molybdate by purificating crude molybdic acid
【摘要】 以含钼废催化剂提取的粗钼酸为原料,采用多次酸洗→氨浸→酸沉结晶的工艺制备高纯钼酸铵,所制备的产品达到GB3460-82的MSA-1级标准,钼的直收率超过95%.
【Abstract】 Higher purity ammonium molybdate was produced by purificating crude molybdic acid recovered from spent catalysts containing molybdenum.The process included several times acid pickling,ammonium leaching and ammonium molybdate crystallizing.Ammonium molybdate gained by the process accords to MSA-1 of GB3460-82.The recovery rates of molybdenum were higher than 95%.
