| Abstract: | Resource distribution,demand of rhenium element in global and China,and high-purity ammonium rhenate production technology are introduced.Rhenium recovery from sewage acid in Daye Nonferrous Metals Co.,Ltd.is introduced in detail.After rhenium recovery,rhenium concentration in waste acid was less than 0.8 mg/L,and rhenium concentration in residue was more than 1%.Rhenium content in leachate from slag was more than 200 times richer than that in raw materials.Mass fraction of ammonium rhenate product was stably more than 99%,and comprehensive recovery rate of rhenium reached 65%.Impurity thallium element in ammonium rhenate prepared by the process was 20 times higher than 4N grade,which needed further technical research. |
