Smelting Wikipedia

Smelting 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.

British Lime Association (BLA) part of the Mineral

Iron ore fines are mixed at the ironworks with limestone and other minerals and pre-fired at low temperatures to form a sinter, i.e. agglomerates that can then be fed to the blast-furnace. Finely divided quicklime is often added to the sinter mixture to assist in binding the material to improve productivity and give a stronger sinter structure.
