Answer:
Smelting: is a form of extractive metallurgy to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke, charcoal, and coal.
Roasting is a pyrochemical process in which the ore is heated in the presence of oxygen or air is below its melting point roasting is done in reverberatory furnace. ... Smelting is a pyrochemical process, in which the ore is mixed with flux and fuel then is strongly heated.
