Aluminum is one of the most destructive mining products in the world. Although aluminum only occurs in aluminum ore (bauxite) in densities of 3 – 5% (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.
