As a result of these efforts, the "B" side of the 93 plant was extensively modified and started up in 1982. Although the coarse coal circuit cleaning equipment was not changed, it now processes a minimum coal size of Ve in. (3.15 mm) instead of 1/4in. (6.35 mm).
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine – a pit, and the
