Characterization of the coal resources of South Africa

2009-8-26 · Estimates for South Africa’s coal recoverable reserves made in 1999range from nine to 59 billion tons; latest estimates by the MineralsBureau suggest that 33 billion tons is a more likely figure. As muchas 70% of that coal is located in the Waterberg, Witbank, andHighveld coalfields, as well as lesser amounts in the Ermelo, FreeState and Springbok Flats coalfields. However, the Witbank andHighveld coalfields are approaching exhaustion (estimated 9 billiontons of recoverable coal remaining in each), while the coal qualityor mining conditions in the Waterberg, Free State and SpringbokFlats coalfields are significant barriers to immediate, conventionalexploitation. New extraction technologies, technologies exploitingthe energy content of the coal
