    The effect of surface oxidation of copper sulfide minerals ...

    The most common copper minerals in the oxidized zone are azurite (Cu 3 (CO 3) 2 (OH) 2), cuprite (Cu 2 O), malachite (Cu 2 CO 3 (OH) 2) and tenorite (CuO), etc. Beneath the oxidized zone, some dissolved copper is precipitated as secondary or supergene copper minerals. This enriches the sulfides, making a secondary enrichment, or transitional zone.

    Developments in the physical separation of iron ore ...

    Oxidized iron ores are much more difficult to upgrade by magnetic separators, because their magnetic susceptibilities are only about 1% or less of that of magnetite. In oxidized iron ore separation, it is therefore important to create magnetic fields with high intensities and high gradients to achieve higher iron recoveries.

    Primary Copper Smelting

    In fire refining, blister copper is usually mixed with flux and charged into the furnace, which is maintained at 1100°C (2010°F). Air is blown through the molten mixture to oxidize the copper and any remaining impurities. The impurities are removed as slag. The remaining copper oxide is then subjected to a reducing atmosphere to form purer copper.

    Copper Simple English Wikipedia, the free encyclopedia

    Copper is expelled from the body easily, so it does not build up in toxic effects. Preparation. Copper is sometimes just taken out of the ground and shaped into objects. But most copper is not in a metal form in the ground. Chalcopyrite is the main copper ore. It is heated with air to separate the iron as iron(II) oxide. Some copper(I) oxide is made.
