Flotation of lead-zinc sulfide ore . In the beneficiation process, the sulfide lead-zinc ore is mainly flotation. Among them, the proportion of zinc ore in most lead-zinc ore is higher than that of lead ore. Therefore, in the actual process, the method of "suppressing zinc and floating lead" is generally adopted. Main principles to deal ...
