Froth Flotation Analysis of Oxidized Lead-Zinc Ore

In the flotation process of oxidized lead-zinc ore, sulfide is added first to vulcanize the mineral for subsequent flotation treatment. The following problems should be paid attention to in the vulcanization treatment of lead oxide: first, white lead ore, lead alum and lead molybdate are easy to vulcanize, sodium sulfide, calcium sulfide, sodium sulfide and other vulcanizing agents can be used ...

treatment. In the flotation process, a number of reagents are seen as a means ofdepressing pyrrhotite. However, the complex surface chemistry of the nickel-copper ores appears to challenge the effectiveness and consistency of these reagents; in many cases, testing indicates that pyrrhotite continues to float when it is not supposed to. Some ofthe contradictory results may be attributed to the ...

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing ...
