LIMESTONE is a very essential raw material for the meta-llurgical industry as flux and in the manufacture of cement. Large deposits of limestone are located all over the country and are being worked out. In addition to this, calcareous material like shells and corals are also worked out on the coastal areas wherever it is necessary. Usual gangue associated with limestone is silica which is removed only by flotation methods. In addition to this, the nature of terrain and the geological structure of the deposit always adds to the alumina content of the ore as the clay gets mixed up with limestone during mining. This is more so when the mines are mechanised. This clay matter may be discarded by screening or washing and wet screening
