Bauxite is the main source of the rare metal gallium. [17] 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. [18]
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.

Bauxite is the only commercial ore of aluminium, and 96 percent of bauxite consumed in the US is used to produce aluminum (metallurgical grade). [2] However, since 1981, none of the bauxite mined in the US was used to make metallic aluminium.

The history of bauxite mining in Ghana dates back to the early 20th century.Bauxite was first discovered in the country in 1921 at Awaso, in the Western North Region.The first operations began in the 1940s, with the Ghana Bauxite Company (GBC) managing the extraction and export of bauxite since then.
Some non-ferrous materials are also used in the iron and steel industries. For example, bauxite is used as flux for blast furnaces, while others such as wolframite, pyrolusite, and chromite are used in making ferrous alloys. [3] Important non-ferrous metals include aluminium, copper, lead, tin, titanium, and zinc, and alloys such as brass.
Business as usual at Guinea's bauxite mines following a coup early this month and China's campaign to reduce domestic energy consumption have mitigated concerns about supply shortages of the ...
