NOUFERROUS METALLURGICAL EQUIPMENT

Fluoritefrom tailings of polymetallic ore is valuable for recovery， but the mineral composition of the tailings is extremely complex and the content of weak magnetic minerals is high. Before fluoriteflotation, a new processing technology of pre-discarding tailings was adopted to remove weak magnetic minerals by intensity magnetic separation. The weak magnetic minerals were discarded as tailings, and the non-magnetic minerals were concentrated as fluorite flotation feed. The results show that fluorite concentrate of 97.58% CaF 2 with recovery 59.61% was obtained by using magnetic flotation combined process of intensity magnetic separation, water exchange and fluorite flotation. The process can obtain good results and has a broad application prospect.
