Bauxite mining in Australia - Wikipedia

Bauxite is a raw material used primarily in the production of aluminium. The bauxite ore is refined into alumina before being smelted into aluminium. Australia is known for its high-grade ore, especially in the Weipa and Gove deposits. The quality of bauxite ore is determined by its available alumina (Al2O3) content. The presence of impurities, which make the ore more difficult to refine, are taken into consideration when grading ore quality. In 2020, IBISWorld predicted that about 49% of bauxite mined i

Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
