9/4/2012The extraction of Iron and its impact on the environment GENERAL OVERVIEW Impacts on the environment due to the extraction of iron from haematite does not only start during the extraction of iron from the ore - it starts when the raw materials are being mined and transported The following are problems which arise from these processes: The enriched ore is roasted with just enough air to convert the iron sulfide to iron(ll) oxide: The solid mixture is then mixed with calcium carbonate (limestone) silica (sand) and heated to 1300 K The iron forms a silicate slag and the copper(I) sulfide melts and sinks to the bottom of the furnace
