Bauxite has also seen growing use as a proppant in recent years. Proppants are used in the hydraulic fracturing process to "prop" open rock fissures allowing natural gas or oil to flow out. Bauxite is sintered in a rotary kiln in order to harden the material so that it can withstand the extreme pressures it will be subjected to.

Mining and Refining – Bauxite Residue Management

It is primarily composed of the insoluble fraction of the bauxite ore that remains after extraction of the aluminium-containing components. Iron oxides (10 – 30%), titanium dioxide (2 – 15%), silicon oxide (5 – 20%) and undissolved alumina (0 – 20%) make up the residue, together with a wide range of other oxides which will vary according to the initial bauxite …

The aluminium industry: A review on state-of-the …

2.2.1. Mining process. Aluminium is rarely found in its elemental form and so requires extraction in order to produce the quantity in demand. The principal ore used for aluminium extraction is bauxite, accountable for …

The processing of high silica bauxites

The Bayer process is the principal method for the production of alumina from bauxite worldwide. The modern version of the process (developed in the 1880's) still maintains the key steps of dissolution of alumina-rich minerals into hot caustic solution, separation of the insoluble phases, followed by gibbsite precipitation and calcination of …
