  • Ore deposits

    An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining ; they are then refined (often via smelting ) to extract the valuable element, or elements.

  • extraction of copper from ore

    Jun 17, 2007 It is somewhat complicated. I recommend reading the Wikipedia article below for more detail. A simplified explanation (perhaps overly simplified); the concentration of copper in most ore is fairly low and it needs to be concentrated for extraction, oxide ores can be concentrated relatively inexpensively by leaching with sulfuric acid, while sulfide ores are resistant to leaching

  • 19.1 Occurrence, Preparation, and Properties of Transition

    The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80–100 feet high and about 25 feet in diameter ( Figure 5 ) in which the roasted ore, coke, and limestone (impure CaCO 3 ) are introduced continuously into the top.
