Coal tar - Wikipedia

Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses. Medicinally it is a topical medication applied to skin to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy. Industrially it is a railway tie preservative and used in the surfacing of roads.

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 ...
