Metal Melt Pour: Life of a Casting

Smelting is the process of removing a metal element from mined ores. Most metals are found as veins in rocks, or as parts of other elements. Smelting is the first step of extraction. Melting is what is done with metal alloys or pure metals. Scrap is melted, ore is smelted. Pig iron is the rough iron ingots created from iron ore smelting.
