| Abstract: | Using wet process phosphoric acids from phosphate rocks with various magnesium removal rates to decompose phosphate rock the concentrated superphosphates were produced by ripening with concentrated acid.The changes of compsoition of reactants with different MgO/P2O5 ratios during ripening time were determined;the influences of magnesium on decomposition rate of phosphate rock, product's properties, and ripening time were analyzed; and the related process conditions were discussedelementarily. |

| Keywords: | Phosphate rock Concentrated superphosphate Magnesium oxide |
