摘要：NOVELTY - A phosphate is produced by performing concentrating process to obtain concentrated phosphoric acid, using extracting agent to perform multi-stage extraction to the concentrated phosphoric acid to obtain extracting organic phase, subjecting the organic phase to washing process using detergent to obtain phosphoric acid organic phase, and adding alkaline reagent to phosphoric acid organic phase for organic lunar phase formation reaction. USE - Method for preparing phosphate (claimed). ADVANTAGE - The method does not need agent to reach high extraction yield, has less waste liquid and reduced energy consumption, and saves cost.
