Beneficiation of limestone plant rejects for value addition
In general, the process flowsheet for beneficiation of limestone consists of crushing and screening, washing and scrubbing, grinding and classification and flotation [7]. Gravity concentration processes like jigging and tabling can be adopted if there is a considerable specific gravity difference between the desired and undesired minerals [1].
