Bauxite mining Aluminium production begins with bauxite, the "aluminium ore". Most bauxite is mined in ... is extracted from bauxite via a process called refining, composed of two steps: a digestion process, using caustic soda, which allows the separation of aluminium hydroxide from the socalled "bauxite residue", followed by a calcination step which removes the water content in the ...

It is used to process mine pit and plant samples. Up to 15 kg of dry samples are entered into the automated system, after which all processes – including crushing, splitting, milling, fused bead making, XRF analysis and fourpoint LOI – are fully automated.

· The mining industry contributes 2 to 3 percent of global CO 2 emissions and has a large role to play in emissions reduction. Within the industry, much of the focus to date has been on portfolio shifts (that is, divestment of coal assets); however, the industry is facing increasing pressure from regulators, investors, and customers to decarbonize operations.

Bauxite deposits are mainly found in a wide belt around the equator. Hydro's bauxite mines are loed in the state of Pará, in the northernmost part of Brazil. A significant portion of Hydro's bauxite is further processed in the company's own plants, but some of it is also sold directly to other companies.
Other bauxite deposits occur in northern Western Australia, New South Wales and eastern Queensland but are currently uneconomic to mine. Australia's alumina refineries are loed in Western Australia (Kwinana, Wagerup, Pinjarra and Worsely) and Queensland (QAL and Yarwun) and its aluminium smelters are loed in Tasmania (Bell Bay), Queensland (Boyne Island), Victoria (Portland) and New ...
