Bauxite mining can pollute the air, water and soil, thus directly affecting the environment. Air pollution The substances produced during the bauxite mining process include dust, sulfur dioxide (SO2), and nitrogen oxides (NOx). The mining and beneficiation of bauxite do not involve the use of chemical reagents and produces no odors.

Bauxite is a rock containing the hydrated oxides of aluminum; gibbsite, diaspore and boehmite (Al2O3.xH2O). Bauxites contain 55 – 61 % Al2O3, 10 – 30 % combined water, 1 – 25 % Fe2O3, 1 – 3 TiO2 and 1 – 12 % SiO2. Bauxites with low SiO2 are desirable. 6.

Washing and beneficiation (further treatment of the ore to concentrate the minerals) if necessary. Delivery to export or to local refineries. Approximately 165 million tonnes of bauxite are mined each year. Bauxite is generally transported to refineries by conveyor, rail, or ship. Some alumina refineries are located close to their bauxite mines.

The term bauxite ore is applicable to bauxites, which are economically mineable containing not less than 45-50% Al2O3 and not more than 20% Fe2O3, and 3-5% combined silica. The term alumina refers to pure Al2O3 containing 52.9% Al and 47.1% O. Bauxite deposits originate from weathering or soil formation with enrichment of aluminum.
