  • Ore Refining an overview ScienceDirect Topics

    The recovery of metals from sulfide-rich ore bodies proceeds through a series of steps: from mining to crushing to mineral recovery (i.e., concentration), followed typically by smelting of the sulfide concentrates and thence to metal refining; although the nature of the ore body dictates the processes used to extract metals from ores, each of

    Metallurgy Metallurgy Refining: Refining is the final procedure for removing (and often recovering as by-products) the last small amounts of impurities left after the major extraction steps have been completed. It leaves the major metallic element in a practically pure state for commercial application. The procedure is accomplished in three ways: refining by fire, by electrolytic, or by

    Ferrous metallurgy is the metallurgy of iron and alloys.It began far back in prehistory.The earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from at least Greece to India, and more
