Abstract: 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%.
