  • Bauxite The Aluminum Association
    ResourcesEnvironmentFutureDiscoveryBauxite ore is the worlds primary source of aluminum. The ore must first be chemically processed to produce alumina (aluminum oxide). Alumina is then smelted using an electrolysis process to produce pure aluminum metal. Bauxite is typically found in topsoil located in various tropical and subtropical regions. The ore is acquired through environmentally responsible strip-mining operations. Bauxite reserves are most plentiful in Africa, Oceania and South America. Reserve

    The most commonly used models for bauxite mining in Guinea are the 2200 SM and the 2500 SM, according to Wirtgen. “The first is compact yet powerful, with a 2.2 m-long cutting drum and 708 kW of engine power. It is able to cut rock with unconfined compressive strengths of up to 50 MPa, ideal for medium-sized mining operations,” Wirtgen said.

  • Mining and Refining Process

    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.
