Merriespruit Tailings Dam Failure, ia, South Africa. Figure 1: Merriespruit tailings engulf the town. Introduction. On the 22nd February 1994 the Merriespruit tailings dam failed by overtopping as a consequence of heavy rains causing a flowslide (static liquefaction) of part of the embankment (Davies 2002).

Earlier on 11 September 2022, a tailings dam collapsed at the closed Jagersfontein diamond mine in Free State, South Africa. The tailings flowed over 8km and left a path 1.5km wide, entering several streams and rivers including the Prosesspruit, before continuing to the Kalkfontein Dam which is used for drinking water and …

The pH of mine tailings soils and the stream sediments at New Union Gold Mine was found to be acidic and the pH range was 3.93 to 6.28 (fig. 2). The acidic nature of the mine tailings would provide adverse conditions for the growth of plants and grass that may be used for the re-vegetation of the mine tailings.

Between 2am and 6am on 11 September, 2022, residents of Charlesville and Itumeleng in South Africa's Free State province heard a deep rumbling sound. Shortly after, a massive wave of tailings sludge crashed into the two, sweeping away four community members, covering farmland and grazing fields, and destroying multiple homes.

The formation of AMD can be prevented by reducing oxygen diffusion into the mine tailings (Nyquist and Greger, 2009; Sahoo et al., 2013b), which seems to be difficult in the case of South Africa as the tailings dams are not sealed and are exposed to rainwater (Rösner, 1999; Rösner et al., 2001; Naicker et al., 2003; Abiye, 2014).
