The other class, called calcic skarns, are the replacement products of a limestone protolith with dominant mineral assemblages containing Garnet, Clinopyroxene, and Wollastonite Rocks that contain garnet or pyroxene as major phases, are fine-grained, lack iron, and have skarn-like appearances, are generally given the term skarno
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
