摘要：
For the production of potassium magnesium phosphate from phosphoric acid, potassium salts and basic magnesium compounds, these are reacted in a mixture of recycled mother liquor from the potassium magnesium phosphate crystallization and of fresh water, with adjustment of the pH-value of the reaction mixture to 7.2 up to 8.5 through addition of quickly reacting basic compounds, in the presence of potassium magnesium phosphate seed crystals, whereupon the product is separated from the mother liquor and from this a part is recycled to the process start, and the rest is removed.
