The primary source of aluminum is an ore known as bauxite. An ore is any naturally occurring solid material from which a metal or valuable mineral can be obtained. In this case, the solid material is a mixture of hydrated aluminum oxide and hydrated iron oxide. Hydrated refers to water molecules that are chemically bound to the two compounds.Get Price
Sep 21, 2018 · Smelting is a crucial step in aluminum extraction, and without it, it would be extremely difficult to access aluminum in the first place, let alone use it as a building or commercial material. This is because while aluminum is the third most abundant element following oxygen and silicon in the Earth's crust, it is actually rarely found naturally in its native form.Get Price
Start your own smelting business to make money from scrap metal. Since smelting involves heating metals to the point of liquidation, special permits and safety precautions are required. With the right equipment and planning, it's possible to process copper, brass and steel among other metals into ingots for sale to retail and industrial customers.Get Price
May 08, 2014 · Aluminum is the most abundant metallic element (8 wt%) in the earth's crust. It is found in nature in a wide variety of minerals combined with oxygen, silicon, and other metals. Because all the aluminum compounds are very stable chemically, aluminum is never found as a metal in nature.Get Price
