| Abstract: | The preparation method of phosphate magnesium fertilizer is studied which raw material flotation tailings of low and medium-grade phosphate rock is decomposed directly by mixed acid both phosphoric acid and sulfuric acid. The mineralogical performance of flotation tailings, the basic principle of decomposition, process conditions, and product quality are discussed. The preparation feasibility of the phosphate magnesium fertilizer is analyzed from flotation tailings of low and medium-grade phosphate rock. |
