Haldar ( 2013) described mineral processing «as the value-added processing of raw material (run-of-mine ore) to yield marketable intermediate products (e.g. copper concentrate) or finished products (e.g. silica sand) containing more than one valuable minerals and separation of gangue (tailing).».
4. Underground mining - occurs when minerals are deep below the ground. This is the most widespread method used for mineral extraction and involves digging a main shaft, with parallel shafts allowing the maximum extraction of minerals. 6. Hydro-mining - involves using high pressure water to blast against the face of seams to remove …

The purpose of the dewatering system is to increase the concentration of the solid discharge removed from the pulp in order to increase the amount of water recovered. Owing to several factors, efforts are being made to increase the efficiency of the recycling of 'used' water (Rao and Finch, 1989): (1) mineral processing plants can consume a ...
