• The Process of Mining Bauxite

    Smelting Extracting and Refining AluminumBillet DevelopmentExtrusion ProcessStep 1. Billet Pre-heating Billets are first cut to the desired length based on the product specifications. Then billets are moved to a tunnel heater and must be heated to approximately 800-925° F. The exact temperature is based on what the make-up of the aluminum is. Step 2. Extrusion After a billet reaches the desired temperature, it is transferred to the loader where a thin film of smut or lubricant is added to the billet and to the ram, to prevent sticking together. Then the billet is transferred to the cradle. A set of die
  • Mining and Refining Process

    Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location. Before mining can commence the land needs to be cleared of timber and vegetation.

  • Mining and Refining Process

    The bauxite residue sinks to the bottom of the settling tanks, then is transferred to the washing tanks, where it undergoes a series of washing stages to recover the caustic soda (which is reused in the digestion process). Further separation of the pregnant liquor from the bauxite residue is performed utilising a series of security filters.

  • Bauxite Mining and Alumina Refining: Process Description

    Process Description: Bauxite MiningProcess Description: Alumina RefiningPhysical RisksChemical RisksBiological RisksErgonomic RisksPsychosocial RisksBauxite is the principal ore of alumina (Al2O3), which is used to produce aluminum (Al). It is composed of hydrated aluminum oxides, hydrated aluminosilicates, iron oxides, hydrated iron oxides, titanium oxide, and silica. It contains mixtures of various minerals such as gibbsite, boehmite, hematite, goethite, Al-goethite, anatase, rutile, ilmenite, kaolin, and quartz. Bauxite is a residual rock formed from the weathering of various igneous, sedimentary, and metamorphic rocks. These parent rocks have been ex

    ResourcesEnvironmentFutureDiscoveryBauxite is usually found near the surface of terrain and can be strip-mined economically. The industry has taken a leadership role in environmental conservation efforts. When the land is cleared prior to mining, the topsoil is stored so it can be replaced during rehabilitation. During the strip-mining process, bauxite is broken up and taken out of the mine to an alumina refinery. Once mining is complete, the topsoil is replaced and the area undergoes a restoration process. When the ore is mined in forested areas, an av
