Aluminum Production - an overview |

The aluminum production process uses electrical power as major energy source. This electrical energy is generally derived from thermal power plants which work with maximum 30% efficiency. This electrical energy amounts to 148.4 GJ ton − 1 aluminum forming 85% of total energy (174 GJ ton − 1) input.

Bayer process - Wikipedia

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to

Aluminium production process

REDUCTION PROCESS At an aluminium smelter, alumina is poured into special reduction cells with molten cryolite at 950⁰С. Electric currents are then induced in the mixture at 400 kA or above; this current breaks the bond between the aluminium and oxygen atoms resulting in liquid aluminium settling at the bottom of the reduction cell.

A Seed processing plant splits the natural product which comes from fields from the lean harvest. It also calibrates the product with desired sizes and processes 10 tons/hour input product with %95-97 purity. Whereby using Fotosorter (Color-sorter) output purity can reach up to %99.9.. With de-awner machine, awns of barleys are peeled so that seeds germinate easily.
