04/09/2012 · 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
environmental problems. Recovery of iron minerals from the tailings produced in a large iron ore operation is of importance as it will result in environmental and economic benefits which indie the importance of utilising those accumulated fines. An investigation was carried out to determine a possible beneficiation route for Sishen mine iron ore
characteristics requiring suitable beneficiation process to produce quality raw material. Characterization has become an integral part of mineral processing and beneficiation largely depends on the nature of association of gangue with the ore.
