  • Mining and Refining Process World Aluminium

    Aluminium is the most abundant metal in the earth's crust. Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.


    usually is transformed into concentrate at the mine site. Concentrate is an upgraded material. For example, copper ore often has a grade of about 1%. Copper concentrate typically contains 20-25% copper by weight. Metallurgical processing, in which ore or concentrate is transformed into a
