摘　　要：从钼冶炼废酸中高效回收铼一直是研究的热点,本文结合金堆城钼矿中铼回收相关研究,分析了用强碱性阴离子交换树脂和弱碱性阴离子交换树脂吸附回收铼的工艺流程、技术指标和优缺点。目前采用弱碱性阴离子交换树脂直接吸附法,从钼精矿焙烧废酸中回收铼,粗铼酸铵产品经2~3次溶解结晶,制备出合格铼酸铵产品,废酸中铼含量平均为17.86 mg/L,离子交换过程铼吸附率为97.5%,解吸附率为99.7%,总回收率为91.6%,高铼酸铵产品纯度可达99.99%。该生产工艺具有流程简单、生产稳定、技术指标好的特点,具有较好的推广应用前景。The efficient recovery of rhenium had always been a research hotspot.Combined with the related research results of Jinduicheng Molybdenum Company,the differences in technological process,index and technological features of strong basicity resin process and weak basicity resin process are compared and analyzed in this article.At present the direct ion exchange process using weak base resin was adopted for rhenium recovery from molybdenum roasting spraying water.The ammonium perrhenate product was obtained by 2-3 times heat dissolution and cooling crystallization process using crude ammonium perrhenate.The rhenium recovery process was characterized by its simplicity,stabilization and efficiency.According to production statistics the average content of rhenium in spraying water was 17.86 mg/L,the adsorption rate of rhenium was 97.5%in ion exchange process,the elution rate of rhenium was 99.7%and the overall recovery of rhenium was 91.6%.The product purity of ammonium perrhenate reached 99.99%.
