  • Lead processing Mining and concentrating Britannica

    Before lead concentrate can be charged into traditional blast furnaces for smelting, it must be roasted to remove most of the sulfur and to agglomerate further the fine flotation products so that they will not be blown out of the blast furnace Various fluxing materials, such as limestone or iron ore, are mixed with the ore concentrateThe objective of the invention is to provide a process of using sulphur leadzinc containing tailings to prepare sulphur iron ore concentrate, using magnetfloating combination process or magnetgravityfloating combination process to produce sulphur iron ore concentrate containing more than 90% sulphur and iron, using the sulphur iron ore concentrate to produce sulphuric acid, getting 98% CNA Process of using sulphur leadzinc The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfide Approximately 30% of all zinc produced is from recycled sourcesZinc smelting Wikipedia
