Trans. Nonferrous Met. Soc. China 30(2020) 518-534 Extraction and stripping of Cu and Ni from synthetic and industrial solutions of Sarcheshmeh Copper Mine containing Cu, Ni, Fe and Zn ions..., Islamic Azad University, South Tehran Branch, Tehran, Iran Received 16 April 2019; accepted 12 November 2019 Abstract: The extraction and stripping of Cu and Ni ions from synthetic and industrial......
as an extractant and the concentration of HCl was adjusted to 25.48 g/L, the extraction efficiencies of Mo(Ⅵ) and Re(Ⅶ) are 99.84% and 95.19%, respectively. The stripping of molybdenum and rhenium to aqueous phase was investigated using 17% ammonia liquor, the stripping efficiencies of Mo(Ⅵ) and Re(Ⅶ) are about 99.89% and 99.54%, respectively. After stripping, rhenium was separated from molybdenum using D201......
