• Biotite Mineral Geology and Uses ThoughtCo

    In 1847, German mineralogist Hausmann named the mineral biotite in honor of French physicist JeanBaptiste Biot, who explored the optical properties of mica. Many minerals in the Earth''s crust are silicates, but mica is distinct in the way it forms monoclinic crystals stacked to form hexagons.

    Biotite. Biotite is a very common and widespread mineral group. The minerals of the group occur often in metamorphic and igneous rocks. It is much less common in sediments and sedimentary rocks because it yields to clay minerals in the weathering environment. Biotite is one of the two most common members of the mica group.

  • Spotlight on foundation failure in rock slopes

    The mining of the weak zone resulted in acceleration of slope movement. This ended in a tilted, failed rock mass which slumped towards the weathered Biotite zone and truncated at the fault like a broken cantilever. These observations suggested that the failure was likely caused by settlement within the weathered Biotite zone.

  • Assessment of Environmental Impact of the Mineral Mining Industry US EPA

    Mining is accomplished by making a series of evenly spaced crosscuts below the bottom of the ore to be caved, from which raises are driven up to the ore. Then the entire ore body is undercut so that it will slowly cave into the raises (Figure 6). The weight of the ore provides enough force to break it up and move it downward, where it is drawn ...
