Flotation of Lead-Zinc Sulfide Ore
In copper sulfide, lead and zinc ores, there are often associated iron sulfide ore (pyrite, pyrrhotite and marcasite, pyrite (such as arsenopyrite), in order to better flotation of copper, lead, zinc Minerals, often add lime to inhibit iron sulfide minerals. Lime galena, especially galena with a slightly oxidized surface, has an inhibitory effect.
