Calcite Processing by Flotation for Beneficiation

2021-2-26  The Problem with Calcite Processing Flotation The availability of high lime rock is often limited and it becomes necessary to use lower grade sources from quarries favorably located to cement plants. Beneficiation of the lime rock in such cases is necessary to remove impurities and to secure the proper ratio of calcite to other constituents for cement specifications. Flotation
