The vast majority of calcium carbonate used in industry is extracted by mining or quarrying Pure calcium carbonate such as for food or pharmaceutical use can be produced from a pure quarried source usually marble Alternatively calcium carbonate is prepared from calcium oxideMarblemite is a calcium carbonate filler specifically designed for use in cultured marble It comes ready to use with the proper combination of coarse and fine particl The grinding process is controlled to create a distribution of particles that is most beneficial for cultured marble production
