The remediation of acid mine drainage (AMD) in terms of effluents/dumps treatment can be highly complicated due to several factors to be considered such as, but not limited to, its composition. The majority of economically mine deposits are associated with potentially hazardous trace and harmful elements.

The largest waste stream generated by coal mining is waste rock removed to access the coal seam(s). The limited processing required to produce saleable coal from mined ore means that coal mines produce far less other waste types such as tailings as compared to, for example, metal mines (Mudd, 2013).There has, however, been a rapid expansion in the …

Treatment of AMD is typically more expensive than controlling or preventing AMD, as the treatment may be required many years after mining operations have finished. Applying proper controls to prevent AMD mechanisms at the site early in the mining process would be beneficial to minimise the AMD phenomenon.
