BENEFICIATION OF LIMESTONE

Usual gangue associated with limestone is silica which is removed only by flotation methods. In addition to this, the nature of terrain and the geo-logical 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
