Aluminium smelting Wikipedia

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

Exploration expenditure (in 1997-98 prices) peaked at $3.0 billion in 1981-82, and has fluctuated between $1.2 billion and $2.0 billion since the mid-1980s. Overall, between 1975 and 1998, reserves of several major mineral commodities increased substantially
