Extraction of zinc from highly saline and acidic solutions

The separation study was conducted on synthetic solutions prepared in the laboratory using liquid/ 65liquid separation technique. Two radiotracers were used- Zn and 60Co, in order to track distribution of the metals between organic and aqueous phases. The of and the selectivity between and cobalt were investigated in
