The effect of calcium nitrate and phosphoric acid as reaction products to the course of decomposition of kola super apatite by nitric acid
Original language description
Natural phosphates are initial raw material for manufacturing of the phosphoric compounds. One process of their treatment exploits their decomposition by nitric acid. It is primary technological operation in combined NPK fertilizers producing. Increasingconsumption of phosphoric raw materials, their high price and gradual exhausting superior deposits bring decisive claim to their maximum exploitation. For optimizing of existing devices or designing new ones the knowledge of the reaction process kinetics that is not still explained in wide reaction conditions is necessary. This work concerns with reaction products effect to the course of Kola super apatite dissolution in nitric acid.All experiments were carried out in isothermal mixed batch reactor forthe initial phase of the decomposition with close fraction of apatite particles. The solution of nitric acid with addition of phosphoric acid or calcium nitrate was used for the decomposition in such excess that its concentration practic
