Bauxite ore is the world's 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.

Tungsten, or wolfram, is a chemical element with symbol W (referring to wolfram) and atomic number 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, from tung sten "heavy stone". Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical .
