Abstract

The recovery of rhenium from acidic wash solution originating from a copper smelting process using sodium thiosulfate were investigated. Effects of reaction time, reaction temperature, flocculant addition and redissolubility of precipitate on the precipitation of rhenium have been studied. The temperature, Oxidation-Reduction Potential of the solution, reaction time in favor of the precipitation efficiency of rhenium. For the recovery of rhenium, copper is precipitated synchronously with a proportion of arsenate. Fine particles in the solution were slow to agglomerate and particle flocculation aids the precipitation rate of metal sulfide. The precipitation time under particle flocculation wa..
