aluminum processing History, Mining, Refining, Facts
Refining the ore. There are a number of alkaline, acid, and thermal methods of refining bauxite, clay, or other ores to obtain alumina. Acid and electrothermal processes generally are either too expensive or do not produce alumina of sufficient purity for commercial use.

ARTICLE Addressing the Challenge of Bauxite Residue
Mar 11, 2019Though alumina can be produced from bauxite by other chemical processes, the Bayer process is the main industrial route for metallurgical alumina production, as it is the most economical process for purification of bauxite that contains a considerable amount of Fe 2 O 3. Over 95% of the alumina produced globally is derived from bauxite using the Bayer process.

Progress in Research and Development of Alumina Production
Alumina and soda is recovered from the mud, and the sodium aluminate solution produced is recycled into the Bayer process. When using the Series method to treat low grade bauxite, the recovery of alumina is high, alkali consumption is low, and energy consumption is obviously lower than the Sinter method [23

Bauxite
Bauxite is the main source of the rare metal gallium. During the processing of bauxite to alumina in the Bayer process, gallium accumulates in the sodium hydroxide liquor. From this it can be extracted by a variety of methods. The most recent is the use of ion exchange resin. Achievable extraction efficiencies critically depend on the original
