In the Bauxites, aluminium compounds are present as gibbsite (Al (OH) 3), boehmite (AlOOH) and diaspore (αAlO (OH)). ii. Filtration: In this step the mixture is clarified to remove impurities. Other than alumina and silica, all other components present in Bauxite do not get dissolved. The solids which are not dissolved get settled down at the bottom forming red mud.

The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current.
In 2016, minerals extracted in Québec came from 27 active mines and close to 530 surface mining sites (Institut de la statistique du Québec).The value of mineral shipments reached billion, a % increase over 2015. The main metals mined are, in decreasing order of shipment value, gold, iron, nickel, titanium, niobium, copper and zinc.
