What is Acid Mine Drainage (AMD), why is it such a serious threat to South Africa and more importantly WHY has been it been silenced and kept under wraps by the mining industry and South African government for so long? Acid mine drainage (AMD) is the flow, or seepage, of polluted water from old mining areas. Depending on the area, the water may ...

Acid mine drainage (also sometimes referred to as acid rock drainage) is a well-understood process 2. and arises primarily when the mineral pyrite (‘fool’s gold’ or iron disulphide) comes into contact with oxygenated water.. The pyrite undergoes oxidation in a two-stage process, the first producing sulphuric acid and ferrous sulphate and the second orange-red ferric hydroxide and more ...

Acid mine drainage (AMD) has received considerable coverage in the media of late and the number of short courses and workshops devoted to the topic has mushroomed. The current interest was prompted mainly by concern arising from the decanting of contaminated water from the old gold mines in the Krugersdorp area into the Cradle of Humankind.

Acid mine drainage is a chemical reaction that occurs when water passes through a mineral rock containing sulfide. It occurs naturally – particularly in locations such as mines and construction sites where there are plenty of these exposed rocks containing sulfide. Acid mine drainage can sometimes be referred to as rock mine drainage.

Acid Mine Drainage is one of the serious issues caused by mining activities and often reported in the last few decades in South Africa [11] [12] . Jan van Riebeeck from the Dutch East India Company visited the South Africa continent and set the region as Cape of Good Hope in 1652, leading to the Netherlands Cape Colony [56] .

economy. South Africa possesses large natural reserves of various metals and coal, and therefore hosts substantial mining activity (McCarthy, 2011). As a consequence of the types of ores in South Africa, which are often sulphide-based, mining operations, currently operational and abandoned, have led to the formation of acid mine drainage (AMD).
