| Abstract: | Process to recover rhenium from rhenium-rich slag and prepare rhenium products was studied. Effects of agent concentration, phase ratio, and time on extraction and stripping of rhenium extraction were investigated. Preparation of ammonium perrhenate by crystallization was explored. The results show that rhenium leaching rate during pressure leaching is 98% above. Rhenium extraction rate is 99.98%, and rhenium stripping rate is 99% above under the optimum condition. Purity of ammonium perrhenate is 98.7%. |
