  • Zinc Mining and Processing: Everything you Need

    The rising cost of processing Australian intermediates led MIM to withdraw first from copper and then lead-zinc smelting activities in Europe. These, plus improvements at MIM's coal operations, encouraged Xstrata to make an offer for the Group which took effect in mid-2003. Swiss-based and and partially owned by Glencore International, Xstrata has widespread ferroalloy, zinc and coal

  • How lead is made - material, used, processing,

    Therefore much lead ore is obtained as a byproduct of other metal mining, usually zinc or silver. Only half of all lead used yearly derives from mining, as half is recovered through recycling, mostly of automobile batteries. Besides the ore itself, only a few raw materials are necessary for the refining of lead. The ore concentrating process requires pine oil, alum, lime, and xanthate
