Aluminum is one of the most destructive mining products in the world. Although aluminum only occurs in aluminum ore (bauxite) in densities of 35% (meaning that for every ton of aluminum metal produced, 20 to 30 tons of ore are mined and dumped) and mining wastes make up the largest waste stream in the world, the reason aluminum is so destructive has little to do with the actual mine.

Chat OnlineAluminum recovery from scrap requires only 5 percent of the energy required to extract it. Therefore, secondary aluminum production from recycling scrap has the potential to significantly reduce greenhouse gas emissions. The most common source of aluminum scrap is aluminum cans, but automobiles, building materials, and appliances are also
Chat OnlineAluminium is the most profuse metallic part in the earths crust. It is mined from bauxite-contained mining areas since the production of aluminium is entirely reliable on extraction from bauxite. It is not found in free form and is the most abundant metallic element in the Earth's crust. Alumininum is basically obtained by using a technique called the Bayer's process developed by Karl Joseph
