Extraction Methods

  1. Aug 23, 2008 #1
    Recently i have been given an assignment about mining either copper or iron ore. I picked Iron Ore and i can't seem to find much information about which process to use for extracting Iron ore.

    The question on the sheet: Explain/describe what type of mining and ore processing methods you recommend - justify your choice.

    So far for this question I have chosen Open-cut mining, now i need help with the rest.

    my text book says that smelting is often used in the process, and that processing consists of three parts: Concentration, Reduction and Purification.

    p.s i am new to the site, so Hello :)

    hello

    so the main ore of iron is hematite Fe2O3.

    http://en.wikipedia.org/wiki/Smelting

    hint:

    concentration will serve to put the ores together
    reduction will serve to liberate the metal from its oxidised form as an ion (because most metals exist in compounds, and not as elements).
    purification will serve to separate the metal from other unwanted compounds such as sulphides, carbonates,...


    proceed step by step and good luck
