alumíniumérc
Alumíniumérc refers to naturally occurring rocks or mineral deposits from which aluminum can be extracted economically. The primary and most commercially significant source of aluminum is bauxite. Bauxite is not a single mineral but rather a mixture of aluminum hydroxide minerals, predominantly gibbsite, boehmite, and diaspore, along with impurities such as iron oxides, silica, and titanium dioxide. These deposits typically form from the weathering of aluminum-rich rocks in tropical or subtropical climates.
The process of obtaining aluminum from bauxite is energy-intensive and involves two main stages. The first
