Abstract
Methods of producing monocalcium phosphate and products created therefrom are provided. The method includes the steps of mixing phosphoric acid and water with brown mud. Preferably, the phosphoric acid is added to water so that it comprises approximately 3% to about 50% of the phosphoric acid/water mixture by weight, and the water comprises approximately 50% to about 97% of the phosphoric acid/water mixture by weight. The brown mud is added to the phosphoric acid/water mixture in a weight ratio of approximately 1:1 to about 1:3. The method of the present invention results in improved monocalcium phosphate products.
