Question

what is Bauxite? How the transportation and power stations play an important role in smelting of it ?​

Answer 1

Explanation:

HEY MATE HERE IS YOUR ANSWER

Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.

Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery.This is an electrolytic process, so an aluminium smelter uses huge amounts of electricity; smelters tend to be located close to large power stations, often hydro-electric ones, in order to reduce the overall carbon footprint. This is an important consideration, because large amount of carbon is also used in this process, resulting in significant amounts of greenhouse gas emissions. Smelters are often located near ports, since many smelters use imported alumina.
