Take you to understand the flotation process of lead-zinc sulfide ore In the beneficiation process, sulfide lead-zinc ore is mainly based on flotation. Among them, the proportion of zinc ore in most lead-zinc ores is higher than the content of lead ore. The main principles to deal with lead-zinc sulfide ore. The common flotation processes of lead-zinc sulfide ore mainly include several methods: priority flotation, mixed flotation, equal flotation, split-speed branch flotation and separation potential control flotation.
