The Economic Contribution From Iron Ore Mining Industry

(Australian Bureau of Statistics, 2006) This begs the question: Does the economic contribution from the iron ore mining industry compensate for the extensive damage it causes to the environment? When iron ore is extracted from the mines, it is typically in the form of haematite (Fe2O3), goethite (Fe2O3.H2O) and is composed of up to 50% Fe.
