How can aluminium be extracted from its ore
WebRecap of key points about aluminum ore. Aluminum ore, also known as bauxite, is a naturally occurring mineral rock that contains aluminum in the form of aluminum oxide (Al2O3) mixed with various impurities. Bauxite is the primary source of aluminum, which is one of the most abundant elements in the Earth’s crust, comprising about 8% by weight. WebAluminium can be extracted (uneconomically) from some clays but the most common aluminium ore is a material called bauxite. First the aluminium ore needs to be mined, …
