Abstract:
     In the present invention, magnesite replaces serpentine, dolomite and silica as flux fully or partially, and the used amount of magnesite and other flux is determined through calculation according to the difference in components of phosphate rock. Because of the MgO content greater than 80% in burnt magnesite and the reduced flux amount, the depleted rate of P2O5 in phosphate rock in processing is reduced. Therefore, the said method can prepare premium calcium-magnesium-phosphorus manure with phosphate rock.
