How Aluminum is Produced -

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.

Processing of Bauxite Ores To Obtain Aluminum Bauxite, the primary aluminum ore, uses the Bayer Process to extract alumina from the ore. The processing begins with crushing to 1-2 inch particles and wet screening, to remove some silica fines, which are generally present with bauxite.

Base Metal Ore Processing Plant & Equipment (Copper & Lead+)

Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.

Extraction Process of Aluminium from Bauxite Ore

This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda. Aluminium oxide appears in the resulting slurry while all the admixtures settle to the bottom as red mud.

Ore processing – Waihi Gold

Bauxite is then converted into aluminum oxide, or alumina, using natural gas at plants located in the southern United States. After alumina is extracted from bauxite ore, further processing called 'smelting' is necessary to convert it into aluminum. In this process, alumina is dissolved in a solution and a strong electric current is applied.
