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: From mining and transporting of raw materials - Air pollution - Noise pollution - Loss of land (due to mining of haematite, coke and
The solid material generated in large quantities by iron ore extraction is the material that overlies the ore body and the processed tailings . These wastes contain minerals associated with the ore body and host rock, mainly the laterite, and sometimes the clays. Mine waste generally has different physical and chemical properties, resulting in potentially different environmental impacts
The extraction cost of base metals is large and its extraction usually requires intensive investment, the buildup of large infrastructures, and generally produces large environmental impacts (Fig. 3). As an example, we may quote the 10 biggest iron mines in the world and their environmental impacts

Steel production from a premium magnetite concentrate product, as opposed to hematite iron ore, provides a range of significant global environmental benefits. Karara's magnetite concentrate is a premium quality steel-making ingredient that is high grade (66-68%) and is very low in impurities. The reduction of magnetite concentrate to produce steel uses less energy, produces less waste and
