Beneficiation of a low grade limestone sample - ScienceDirect

The upgrading of limestone quality can be done many ways. One way is to crush the limestone to −3 mm size and then to process it in a scrubber and classifier. Another entails grinding the feed to less than 200 mesh and then to carry out beneficiation by a froth flotation method . In the present case a low grade limestone sample was processed using the column flotation technique.
