Smelting maximizes the separation of ore from gangue minerals. The concentrates undergo smelting and converting in a furnace at a high temperature to produce a silicate melt (slag) and an immiscible melt (matte) due to density differences. The flux (limestone) is added to the furnace to reduce the melting temperature in the matte.

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.
May 11, 2019· Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.
