fortunately, the environmental impact of that process can be somewhat balanced out by post-mining rehabilitation, ecient recycling, and generally reducing our consumption. the process: bauxite to alumina to aluminum. aluminum is hidden in an ore called bauxite. its a red dirt and clay mixture commonly found in australia, brazil, and india.
sep 16, 2009 the negative impacts are the production, the need for it, essentially the dependency on it as the depletion of the iron ore increases. the energy used to mine iron depends on the mine system itself, like said, there is no one way to mine any ore that everyone uses. perhaps the way to minimize energy used to mine ore, is to find a way to reuse
