  • Mining and Refining Bauxite Residue Management

    The most important barrier to remediation, use and long term sustainability of bauxite residue management is its high alkalinity. Bauxite residues and the runoff from storage areas can be treated to reduce their pH, further reducing the risk of environmental impacts and facilitating rehabilitation of the disposal area after closure.

    - All about aluminium- products after separating aluminium from bauxite ,Alumina is the most widespread metal in nature: making up about 88% of the earth's crust As a result of nepheline processing, significant volumes of by-products are generated To separate pure alumina, the Bayer process is applied It is based on the following principle

  • What is the industrial seperation process of Bauxite

    Feb 22, 2010· Best Answer: Carbon can't be used (as in the separation of other metals eg iron) to reduce and separate aluminium in bauxite because it is very high in the reactivity series. Instead electrolysis has to be used. Bauxite is converted to pure aluminium oxide (Al2O3) after removing silica, iron and titanium oxides through the Bayer process by using hot sodium hydroxide which converts just
