Mining Events

The 2019 African Exploration Showcase will focus on the metals and minerals critical to the technologies for a low carbon energy future: technology enabling commodities that are commonly referred to as“Critical Metals”.“Critical Metals” is not accurate in that commodities in this basket are not always metals (e.g. graphite); and ambiguous in that “critical” can refer to the significance of the commodity to a technology (i.e.the technology would not be viable without the commodity) as well as the security of supply of the commodity which is influenced by factors that change with time and locality. We prefer to use the term “Technology Commodities”.

In the Karoo coalfields, mining operations that release acid mine drainage (AMD) are threatening groundwater resources. An important parameter controlling the extent and severity of AMD impacts is the natural attenuation of rocks in response to introduced of AMD. Very little is known about such responses for Karoo rocks in saturated and unsaturated conditions, a research gap filled by this paper. Laboratory column leach experiments were used to study the responses of different rock types from Witbank, Ermelo and Highveld coalfields of South Africa. .

Mine water management is a broad topic covering a range of specialist sub-disciplines. In this case, mine water management will focus on groundwater, surface water and process water management within the mining environment, on the water management aspects associated with the varied mine residue deposits as well as on the regulations that govern the use, storage, management, etc. of the water resources.
