A Short Review on Aluminium Smelting and Its Future Prospect in Malaysia Metal Industries

Smelting is process to produce aluminum from its ores. Domestic demand for aluminium had increased during the past several years and expected to grow in the future. Non-ferrous metal like aluminium was important because of desirable properties such as low weight despite the higher cost compared to ferrous metal. This paper presents a review of aluminum smelting in Malaysia industries. The survey covered the alternative aluminum processes including the alumina, electrical energy, some carbon, and possibly some other recyclable chemicals as an input. The outputs are aluminum and varying amounts of carbon oxides. The results introduce the fact of the aluminum industry must be based on discovering a new bauxite fields and the stability of the price of aluminum.
