Economic Coal Resources of the Highveld, Ermelo, South Rand and Sasolburg-vereeniging Coalfields

Comparative ranking of coalfields inside and outside South Africa on exploration level, resource size and infrastructure, for companies deciding where to explore next.

by Grant van Heerden | August 2004

What this report found

A rating and ranking system was applied to South African coalfields and, separately, to the coal bearing countries elsewhere in the Southern African Development Community. The Waterberg ranked highest in South Africa and is the coalfield most worth detailed investigation as Witbank output declines. Botswana ranked highest among the other member states on contained resources and exploitation potential.

What this report found

Cynodon dactylon outperformed Themeda triandra and Hyparrhenia hirta, reaching 100 per cent survival and cover at all three trial sites by 2007 with or without fertiliser. Acacia sieberana reached 97 per cent survival at Kleinkopje Colliery but grew poorly at Optimum and Syferfontein. Planting plugs suits slopes too steep for a planter machine and buffers against pasture grass intrusion.

What this report found

The fine coal dense medium pilot plant was rebuilt at South Witbank Coal Mine and run on fine coal, with tests covering single, double and three stage processing, the effect of recirculating load, magnetite size and losses, separation efficiency and continuous operation. The fast screen could not deliver the required capacity and was replaced by dewatering cyclones to deslime the feed.
