There are several minerals available in the world from which aluminium can be obtained, but the most common raw material is bauxite. Bauxite is a mineral made up primarily of aluminium oxide mixed with some other minerals. Bauxite is regarded as high quality if it contains more than 50% of aluminium .
Aluminium 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, then the bauxite is refined into alumina (aluminium oxide). Large amounts of electricity are used to smelt the alumina into aluminium metal. Properties
Raw Material Mining and Quality Control for Steel. The iron and steel manufacturing process begins with mining raw materials, which must then be carefully processed to ensure quality finished products that meet specifications.There are more than 3,500 different grades of steel with many different physical, chemical, and environmental properties.
