“…ARD seepage effects can manifest in low pH waters (1.4 to 4), with subsequent precipitates of hydrous ferric oxides including efflorescent sulfate salts, and blooms of green filamentous biofilms on the TSF [35] which is the case in O'Kiep. Consequently, the effects of ARD and aggradation by mineralized MTs would affect many communities further downstream [36], therefore reducing the amount of usable water in a country where physical water scarcity is already a concern [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55]. Additionally, the chemical and physical dispersion of PTEs might continue from the TSF for the predictable future unless a mitigation strategy is implemented.…”

One of the environmental challenges in O'Kiep is the increased levels of potentially toxic elements (PTEs) in metalliferous tailings (MTs), which may result in acid rock drainage (ARD) through oxidation. In this study, laboratory-based static tests were conducted on MTs to predict the risk of acid rock drainage potential (ARDP). Mineralogical analysis of the MTs showed that the MTs consisted mainly of quartz, microline, muscovite, albite, anorthite, magnetite, magnesioferrite, gypsum and halloysite-10A. The major oxides, i.
