Extraction Process of Aluminium from Bauxite .
Aluminum is the most abundant metal in the earth's 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 ...

The Environmental Impact of Aluminum (And .
Aluminum (or Aluminium, if you're not from the US) is an abundant element within Earth's surface— but getting it out of the ground is an arduous process, requiring heavy machinery to plow up acres and acres of land. Fortunately, the environmental impact of that process can be somewhat balanced out by post-mining rehabilitation, eﬃcient recycling, and generally reducing our consumption.

How Cane Sugar is Made - the Basic Story
Sugar cane is a sub-tropical and tropical crop that prefers lots of sun and lots of water - provided that its roots are not waterlogged. It typically takes about 12 months to reach maturity although the time varies widely around the world from as short as six months in Louisiana to 24 months in some places. Where it differs from many crops is that it re-grows from the roots so the plant lasts ...

Abstract In an aluminum production plant using the prebaked anode technology, the levels of exposures to PAH in rebuilding of cathode clearly demonstrate the influence of pitch paste temperature and of joint surfaces. Pollution is the highest when hot paste and big joint technique is adopted and the lowest with warm paste and small joint (8.8 μmol vs 1.2 μmol OHP / mol creatinine, respectively).
