What Is Metal Smelting? (with pictures)
Lori Kilchermann Huge blast furnaces are used for metal smelting. Metal smelting is the process of creating metal by heating metal ore. The ore, be it iron, copper or tin, is mixed with a carbon and the mixture is heated to the point of conversion into a liquid form. The liquid is then mixed with a flux, such as limestone, when metal smelting.
