  • Mining and mineral use

    Underground mining is used to recover ores that are deeper into earths surface. miners blast and tunnel into rock to gain access to the ores. how underground mining is approached from above, below, or sideways depends on the placement of the ore body, its depth, concentration of ore, and the strength of the surrounding.

  • Extraction process of aluminium from bauxite ore

    Aluminum is the most abundant metal in the earths crust and is a constituent of many minerals. however, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes. bauxite is the general name given to the hydrated oxides of aluminum. it contains varying amounts of.

  • Aluminium production process

    This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. the ore is loaded into autoclaves and treated with limecaustic soda. aluminium oxide appears in the resulting slurry while all the admixtures settle to the bottom as red.
