The below Cement Rock Beneficiation Process flowsheet represents a simplified flow diagram of a cement plant in which beneficiation of raw materials is employed. Using a crude feed of limestone and/or clay, the flowsheet produces raw clay by multi-stage cycloning, and "Sub-A" Flotation upgrades the impure limestone.

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 raw feed to less than 200 mesh and then to carry out beneficiation by a froth flotation method [4], [5], [6], [7].
