Thungela Resources Limited holds 90% of the thermal coal operations in South Africa with the remaining 10% held collectively by an employee partnership plan and a community partnership plan.
Anglo American plc announces the completion of the demerger of its thermal coal operations in South Africa. Thungela Resources Limited will start trading today through a primary listing on the Johannesburg Stock Exchange under the abbreviated name “Thungela” (Alpha code "TGA”), and a standard listing on the London Stock Exchange (ticker symbol “TGA”).
Summary:
Kleinkopje Colliery.
Five main seams that are numbered in order of deposition from No.1 seam to No. 5 seam are present at Kleinkopje Colliery, this being typical of the Witbank Coalfield1. The coal- seams are separated by sediments of shale, sandstone and siltstone.
Mining Methods
- Truck & Shovel / Loader
- Dragline
Summary:
Kleinkopje Colliery is an opencast mine that uses strip and shovel method to mine the remainder of pillars left during underground mining.

Summary:
The layout of Kleinkopje plant commences at the raw coal tipping area, where coal can be tipped either on the A, B or C tip. The tipped material is then sized down to 150 mm through primary crushing Bradford breaker. The oversize is then subjected to a jaw crusher that also reduces the material size to a top size of 150 mm.

Summary:
Kleinkopje Colliery has five Wemco drums that were installed and commissioned in 1978. Over the years, there have been remarkable changes in mining and geological conditions at the colliery. First, an increase in the percentage of fines was recorded, which resulted in an uneven split or an imbalance in silo levels between material feeding the cyclone (-12 mm) and Wemco drum (+12 mm) sections respectively. This problem was solved by doing modifications around the banana screens to allow finer material to the drums. The imbalance challenge was then followed by spontaneous combustion that takes place in situ and results in low product yield. The results obtained from efficiency tests indicate that although there is a limit in the percentage of -6 mm material in the feed, Wemco drums are still very efficient and applicable to the current mining conditions. These results also suggest that it is essential to lower the throughput when the drums are treating low yielding coal.
