Challenges and opportunities in the recovery/rejection of trace
Fluorine in the talc phase is more problematic due to the natural floatability of talc (Pangum et al., 1997). Initially, an organic depressant, carboxyl methyl cellulose (CMC), was employed to reject fluorine. CMC depressed talc, resulting in a significant reduction of fluorine, but also resulted in low recovery of chalcopyrite (Pangum, 1999 ...Web
