2018-9-14  As a result of work on coal qualities in South Africa, a database was established which enabled a good estimate to be made of the composition of the discard from every mine. The data are presented in the form of histograms of ash, volatile matter and fixed carbon content of the 43 million tons of material which were discarded in 1990.

Characterising the Environmental Risks of Coal

2018-9-5  South Africa still relies heavily on its coal re-serves for power generation, with around 70% of the country’s primary energy consumption being based on coal.  e preparation (also known as the cleaning or processing) of run-of-mine (ROM) coal, generates two di er-ent types of coal processing wastes: discards and ultra- ne slurry waste.  ese wastes are traditionally disposed of to land ll and pose
