aluminium ore benefication process,Bauxite Mining and Alumina Refining - NCBI - NIH

The majority of the bauxite can be mined and processed without beneficiation (further treatment of the ore to concentrate the minerals), but the ore in the north of Brazil and in Vietnam has a high clay content and has to be washed before processing.

Aluminum processing | Britannica

Aluminum processing: Aluminum processing, preparation of the ore for use in various products. Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660° C (1220° F) and a density of 2.7 grams per cubic centimetre. The most abundant metallic element, it constitutes 8.1 percent of the Earth's.

Ore conservation is a major benefit when scrap metal gets recycled .

Once iron ore is removed from the ground, the next production phase is beneficiation. That involves dissolving rock material to get the mineral. Iron in its purest form is then shipped to global markets. Mining and refining metal ores is simply not a sustainable process. It's been well determined that the amount of metals.
