Wastewater, containing toxic as well as valuable metals is discharged as ,acid mine, drainage (AMD) in major mining and industrial operations. This has led to a sharp increase in metal contamination of water reserves and a potential risk of decant water from closed mines is looming in the Western, Central, and Eastern basins of the Witwatersrand, South Africa.

However, ultramafic ,mine, tailings are usually benign (e.g., very low ,acid,-generating potential/high neutralization potential) and pose no substantial risk to the environment with the possible exception of asbestos and chromite ,mine, wastes. Alternatively, point sources with CO 2-rich gasses could be utilized .

Applications of zerovalent iron (ZVI) for water treatment under aerobic conditions include sequestration of metals (e.g., in ,acid mine, drainage) and decolorization of dyes (in wastewaters from textile manufacturing). The processes responsible for contaminant removal can be a complex mixture of reduction, oxidation, sorption, and coprecipitation processes, which are further complicated by the ...

Sulfidation, of CuO NPs with soluble sulfide was also studied. A rapid ,sulfidation, was observed, and the dissolution–precipitation mechanism was involved 82 . Bioavailability of metal‐based NPs is controlled by their environmental behaviors, which depend on many factors mentioned earlier in this section, especially the dissolution in the aqueous phase 83 , 84 .
