In this study, an approximation was made to calculate indicators of the water footprint of gold mining in the municipality of Suárez (Cauca, Colombia), determining that the BWF is 79.91 m 3 /kg of gold extracted and the GWF ranges between 272,125.39 and 404,825.11 m 3 /kg of gold extracted. These values confirm the high impact of gold mining ...

This study investigated the applicability of maghemite and magnetite nanoparticles (NPs) for the removal of heavy metals from mining wastewater. The maghemite and magnetite NPs of 122nm and 74nm were synthesized using a co precipitation method and characterized by Nanometer particle size analysis (NANOPHOX) and TEM, X-ray diffraction (XRD).

Wastewater from these processes can pollute water sources nearby and deplete freshwater supplies in the region surrounding the mine. Some mines, such as the Mountain Pass mine in southern California, have implemented waste-water recycling technologies, resulting in a huge decrease in water demands and liquid waste (Molycorp, 2012).
