  • Metal MeltPour: 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.

    Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.
