Bauxite mining is the foremost open-cast mining and bauxite is the only material for manufacturing aluminum metals and is used as a prominent industrial raw material.
Bauxite mining operations aim to restore the pre-mining environment and respective conditions; returning the original ecosystem as close as possible, in terms of structure, function and dynamics and creating a land-use to benefit the local community. Most operations rehabilitate used areas progressively as mine pits are closed.
Bauxite Hills (QLD) The Bauxite Hills Project on the Cape York Peninsula in Queensland is hoping to take advantage of an expected increase in the demand for Alumina.

In the 1960s, bauxite mining cleared 440ha of publicly-owned land in the Northern Jarrah Forest, but between 2010 and 2019, the figure had surged to 10,420ha – a nearly 25-fold increase. The report warns that if the current trend of bauxite mining continues, it could eventually clear up to 83,000ha of forest and fragment another 337,000ha.

Bauxite grade is an important property determining the ore reserve, mining value and mining technology parameters within an underground bauxite seam, which is a prominent difference between bauxite and coal mines. An orebody demarcating approach was proposed to determine the top and bottom boundaries of bauxite orebody, which consists of the following …
The flowsheet in this study illustrates only the following two steps in the modified Bayer Process: grinding and digestion of bauxite in the sodium aluminate liquor, separation and washing of the coarse red mud residue from …
The AAC welcomed this inclusion but emphasised that this was only a "first step in assigning priority status" as the omission of bauxite stands. ... In a letter to the government on 26 July, the AAC repeated its stance on the importance of bauxite mining in Australia's ability to vie for capital in a competitive global market.
Bauxite mining emits, on average, less than 100 kg CO 2 per tonne of bauxite. Mine operators have adopted a number of strategies to use energy more efficiently and to reduce emissions. These strategies include: Purchase of larger, more energy efficient mining equipment and trucks; Improved maintenance of mining and transport machinery;
Keeping the above characteristics in view, several west coast lateritic bauxite mines of India employ dry crushing−screening process to bring down silica content from the metallurgical grade bauxite [].Recently, a bauxite mine of Guinea known as AGB2A has also adopted the dry beneficiation procedure to cut down silica from about 7% to below 3%, to make this one the …

At the same time changes are occurring in global bauxite supply with new countries and new operators entering the market. Sustainable bauxite mining practices are critical to the global reputation of the industry. Sustainable practices should be perceived and valued as a competitive advantage for all mining companies.
Meanwhile, aluminium is present in more than 35 percent of modern materials and equipment used around the world, making bauxite a highly sought-after resource critical to our modern way of life, and bauxite mining companies key to keeping our world turning. One such player in the bauxite mining space is Compagnie des Bauxites de Guinée (CBG).
In the production of aluminium from bauxite, the intermediate alumina (Al2O3) is produced by a combination process; the alumina is subsequently smelted to aluminium via a …
