  • Patent number: 9653732
    Abstract: A process for producing a phosphate by: introducing oxidic metal(II)-, metal(III)- metal(IV) or compounds with mixed oxide stages selected from hydroxides, oxides, oxide-hydroxides, oxide-hydrates, carbonates and hydroxide carbonates, of at least one of the metals Mn, Fe, Co and Ni with the elemental forms or alloys of at least one of the metals Mn, Fe, Co and/or Ni into an aqueous medium containing phosphoric acid, and reacting the oxidic metal compounds with elemental forms or alloys of the metals to obtain divalent metal ions, removing solid substances, producing an alkali metal phosphate receiver solution with a pH-value of 5 to 8 and metering the aqueous solution into the receiver solution and at the same time metering a basic aqueous alkali hydroxide solution that the pH-value of the resulting reaction mixture is kept in the region of 5 to 8 to precipitate the desired phosphate.
