Maifan stone, an aggregate of a variety of minerals, is the product of the late differentiation of the magma of the calc-alkalic rock, and a half weathering of rocks of the igneous rock. Maifan stone is mainly composed of anorthose and potassium feldspar, secondly is quartz, amphiboles, biotite and by product phosphorus fossil. When the Maifan stone is grinded in to the granularity of 325 mesh, put a grain of itunder the electron microscope, we can see the structure like coral reef or porous structure of sponge. The main chemical components of Maifan stone is inorganic silicon aluminate, including, SiO2, Al2O3, Fe2O3, FeO, MgO, CaOK2O, Na2O, TiO2, P2O5, MnO and so on. It also contains all major elements animals need, such as trace elements: K, Na, Ca, P, Mg, Fe, Cu, Zn, Mn, Mo and rare earth, which amount to 58 kinds. Granularity we can produce is from 0.5 micrometer to 2 micrometer.Mainly applied in: fodder, cosmetics, textile industry, water treatment, decoration, chemicals and so on.
