Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and,History of aluminium - Wikipedia,Aluminium (or aluminum) metal is very rare in native form, and the process to refine it from ores is complex, so for most of human history it was unknown.However, the compound alum has been known since the 5th century BCE and was used extensively by the ancients for dyeing. During the Middle Ages, its use for dyeing made it a commodity of international commerce.Lithium element extraction, mining technique– Acid,,Mining. literally means extraction.Our Mother Earth has lots of resources deep within her and mining is the method of extracting all these valuable resources from the earth through different means.There are different methods to extract these resources which are found in
