Lead smelting - Wikipedia
Plants for the production of lead are generally referred to as lead smelters. Primary lead production begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizingelements to free the metal. Reduction is the final, high-temperature step in smelting. It is here that the oxide becomes the elemental metal. A reducing environment (often p…Mining - Antimony,In modern practice, the intermediate grades of antimony ore of all kinds are smelted in a blast furnace. This is the most important process for the extraction of antimony from its ores. The furnace feed can consist of briquetted fines or flue dust, mattes, mixed ores, oxides, sulfides, and residues and slags,. The large amount of slag formed is beneficial in reducing volatilization losses of,Blast Furnace Smelting Antimony,Jul 01, 2014nbsp018332WQS is the solid waste from the blast furnace, where the antimony concentrates are smelted together with coke, iron ore and limestone. Consequently, WQS was mainly composed of 40.4 of SiO2, 21.8 of Fe 2 O 3, and 21.4 of CaO. DS was also enriched in 30.2 of CaO, which was from the lime cream used for gas desulfurization.
