- 摘要：
- Techniques are applied for the sorption of rhenium from the leaching solution of the fume of calcinating molybdenite concentrate by 201×7 strong base anion exchange resin. By analyzing the main ion from the leaching solution be pretreatmented, the 201×7 strong base anion exchange resin be used in experiment. The influencing factors on the sorption were investigated, with medium pH, the existing form of the ion in the solution and the pH are greatly related to the ion exchange capacity , the result show that the resin not only have higher adsorption rate of ReO4 - , but also have higher separation factor of ReO4 - and MoO4 2- when the leaching solution was pretreated pH at 9.0. The separation factor of ReO4 - and MoO4 2- reached to 980.5. 5%NH4OH+9%NH4Cl solution is a effective desorption reagent for molybdenum, the desorption rate is 96% and nitric acid solution is a effective desorption reagent for rhenium on the loaded resin after desorpted the MoO4 2- ,the desorption rate of ReO4 - is 98%.
