zinc ore benefication process

zinc ore benefication process

Low-grade lead-zinc ore pre-beneficiation process. Lead-zinc ore is a common non-ferrous metal mineral. In the past, the beneficiation of lead-zinc ore was dominated by flotation, but with the passage of time, today's lead-zinc ore is seriously depleted, many low-grade lead-zinc mines fail to meet the grade requirements of flotation.Moreover, the national environmental protection requirements ...
