• Where do metals come from

    Sometimes huge amounts of ore are needed to make a small amount of metal – most copper, for example, exists in sulphide ores that contain as little as 0.25% copper. The metal then has to be extracted from the rock using furnaces and electrolytic processes. Finally, before the metal can be used, it often has to undergo further processing.
