    Bauxite Mining. Scrapers and small excavators are used to remove the remaining overburden and expose the caprock. Depending on the depth of the caprock, it can be broken by blasting, or simply removed with scrapers and excavators. The bauxite is then mined using excavators or loaders to load the bauxite onto haul trucks and transported to the

    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. Reserves are projected to last for ce
