Abstract >Magister Scientiae - MSc - Mining has a lengthy history in South Africa, and subsequent beneficiation processes have been conducted with little regard for the environment, thus leaving the land with un-rehabilitated abandoned mines. Currently, most of these abandoned mine sites are no longer operational and they continuously contaminate soil, air and water resources in various areas where mining took place. This study looks at the treatment of contaminated mine water using the Dispersed Alkaline Substrates (DAS) which is a new South African technology that uses a variety of substrates to neutralize and raise the pH of mine water while lowering the solubility of potentially dangerous metals.
