Significance of iron smelting
Smelting is a process of applying heat to an ore, 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. The reducing agent is commo… WebBoliden is a leading European metals company with core expertise in exploration, mining, smelting and recycling. The main metals are zinc and copper.
