Bauxite

Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. Bauxite is primarily comprised of aluminium oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percentage of the world’s bauxite production is refined through the Bayer chemical process into alumina. Alumina is then refined into pure aluminium metal through the Hall–Héroult electrolytic process.

Aluminous laterite

The low grade bauxites or laterites are used in cement manufacturing industry. The cement sector can offer both industrially mature and industrially promising uses for bauxite residue, BR.

Manganese

Manganese easily reacts with water and air. On Earth, manganese is never found as a free metal, but it is found in a number of minerals.  The most important of these minerals is pyrolusite, the main ore mineral for manganese. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.

Gypsum

Gypsum is a soft sulphate mineral composed of calcium sulphate dehydrate. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.
