Beneficiation of a low grade limestone sample -

2011-9-1  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 raw 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.
