Options in this strategy are concerned with beneficiation of reactive silica or bauxite pre-treatments. They are, by their nature, largely dependent on the mineralogy, liberations and associations of the minerals in the bauxite ore. As such, they will find specific applications for particular bauxites; for example the washing and screening of ...

Bauxite tailings, also known as bauxite residue, red mud, red sludge, or alumina refinery residues (ARR), is a highly alkaline waste product composed mainly of iron oxide that is generated in the industrial production of alumina (aluminium oxide, the principal raw material used in the manufacture of aluminium metal and also widely used in the manufacture of ceramics, abrasives and refractories).

Beneficiation. Most bauxites considered economic require minimal or no beneficiation. Beneficiation of lateritic materials may involve dry screening to remove fine particles with higher silica contents, or simple washing to remove adherent clay minerals.
Beneficiation of Bauxite – Upgrading of Recoverable Al2O3 Dr. Stephan Buntenbach1, Thomas Baumann, Fred Donhauser AKW Apparate+Verfahren , Germany 1 Abstract Bauxite deposits are commonly classified in three genetic types according to mineralogy, chemistry and host-rock lithology.
Bauxite with average thickness of 5m occurs in low lying plateaus and hillocks with low overburden (2m), which canbe easily mined by simple excavators without any drilling-blasting. ROM requires dry or wet beneficiation to eliminate a part of silica (kaolinite) rich fines to produce quality ore for export.
The more is the silica, higher is the soda consumption which increases the cost of alumina production. Physical beneficiation techniques are employed to reduce the reactive silica content of bauxite. Based on several investigations it has been made possible to remove ~30% of silica with 92% recovery depending on the characteristics of the ore.

Since bauxite is a naturally occurring mineral, it has a number of impurities, like iron, silica, Titania, calcium, and small quantities of phosphorous, sulfur, zinc, magnesium and various carbonate and silicate minerals. These impurities not only create quality problems, but also increase production costs, besides causing environmental pollution.

The silica present in the bauxite tends to be concen-trated in the finer grained fractions, and this charac-teristic makes bauxite amenable to beneficiation by screening techniques. Pearson' has reported that in a bauxite of average composition of 1.58% silica, the minus 100 mesh fraction analysed a silica content as high as 10.30%.
