· Various metals have processes of smelting. For iron, once the ore is obtained through open cast or underground mining, it's conveyed up to the surface for crushing, washing, and then taken to the smelter. At the smelter, the crushed ore is put into a blast furnace along with limestone and coke, and subjected to hot air blasting and heat, and it turns to molten iron. Then its tapped from the ...
