The coking coal resources can be augmented by recovering extra low ash coking coal from washery middlings by suitable beneficiation processes (Jha, 2012).This possibility has been established from tests. The middlings were crushed to 13 mm and 3 mm and thereafter subjected to float and sink tests. The results are presented in Figure (a).

Acid mine drainage (AMD) is one of the most serious environmental problems in mining worldwide. One of the largest unexploited coal basins in the world is located in Moatize. It contains about 23 billion metric tonnes of coal. The coal mining there is done in riparian sections of the Zambezi River basin, making it particularly vulnerable to pollution. Much of the coal waste is produced by a ...
