摘要： This invention relates to a process for producing a granular phosphate fertilizer by reacting and granulating simultaneously a mixture of a basic material which contains acid-soluble CaO and acid-soluble MgO, and also acid-soluble SiO.sub.2, with phosphoric acid and/or an acidic phosphate in such a mixing ratio thatA/MO=0.05-0.45[in which MO represents moles of the acid-soluble alkaline earth metals in the basic material (calculated as their oxides) and A represents moles of the phosphoric acid or the free phosphoric acid derived from the acidic phosphate (calculated as P.sub.2 O.sub.5)]. This process makes use of industrial wastes, as the starting basic material, such as slag discharged from metal refining and fly ash. The granular fertilizer obtained by the process is high in granule hardness, easy to handle, and high in phosphate fertilization effect and gives an effect on improving acidic soil.
