  • Mining and Refining Aluminum HowStuffWorks
    CompositionGeologyProductionUsesAluminum isn't found in nature as a pure element. It exhibits relatively high chemical reactivity, which means it tends to bond with other elements to form compounds. More than 270 minerals in Earth's rocks and soils contain aluminum compounds. This makes aluminum the most abundant metal and the third most abundant element in Earth's crust. Only silicon and oxygen are more common than aluminum. The next most common metal after aluminum is iron, followed by magnesium, titanium an­d manganese.­ Th
  • Open Pit Mining an overview ScienceDirect Topics

    An open pit mine could recover almost 90% of the oil shale in a very thick deposit [17]. It is said that strip mining could provide an even higher recovery. Shown in Fig. 8.8 is an open-pit mine used to explain the process of mining the oil shale. The overburden is drilled and blasted loose over an area above the oil shale zone and the load is
