Fe 3 O 4 coke carbon C both fuel and reducing agent. hot air for the oxygen in it to burn the coke. O 2 limestone calcium carbonate to remove certain impurities like silica
Read More2 Smelting is usually a two-stage process as described here although single-stage methods with lower energy use and emissions are also used. After mixing with limestone the filtered concentrated ore is roasted in air or oxygen-enriched air on a moving belt. Most of the sulfide is converted to leadII oxide

Read MoreAn oxide k s a d is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. Oxide itself is the dianion of oxygen an O 2 atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of 2. Most of the Earths crust consists of solid oxides the result of elements being oxidied by the oxygen in air
Read MoreSmelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores including silver iron copper and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behind
