continuous mining of calcium carbonate

continuous mining of calcium carbonate

Most calcium carbonate occurs as limestone, however, heat and pressure can result in the metamorphic form, marble. Calcium carbonate is generally mined as limestone or marble depending on application. Its chemical impurities, size distribution and physical makeup dictate its end use. Calcium carbonate is mined for use in the paper and paint industries as a filler and coating agent, and in plastics for …

    What is calcium carbonate and how can it affect mining

    Fortunately, there is a simple and effective solution for calcium carbonate problems in mining operations. AHydrosmartwatersofteningsolution uses an electromagnetic field to break the bonds in calcium carbonate, and so unblocks pipes downstream of the treatment site while also preventing rescaling. This process improves the viability of water recycling operations and means that mines can make use of …
