They concluded that improvements in iron ore mining and direct water consumption are vital in water reduction. Leenes et al. found a high WF of electricity production in a steel mill. So their recommendation for reducing WF was to replace energy sources with sources of lower WF, such as solar, wind, and geothermal energy. ...
In many cases, most of the water used in mines is converted into wastewater. The type and amount of toxic and heavy elements in mine effluents depend on the type of ore extracted and chemicals used during processing ( Kobya et al., 2010).In addition, other factors such as the type of method used for mineral processing, mine …
Two interrelated problems exist: the non-renewability of phosphate rock as a resource and the excess phosphate in the water system lead to eutrophication. Removal and recovery of phosphorus (P) from waste streams at wastewater treatment plants (WWTPs) is one of the promising solutions. This paper reviews strategies for P recovery …
