Di-calcium phosphate by direct acidulation of

Di-calcium phosphate was obtained in the pilot plant by this method without cyclic mixing or filtration. A product averaging 40 percent total P205, 33*2 percent citrate soluble P^O^ and 92 percent PgCy availability was obtained. A preliminary cost estimation indicated the proposed di-calcium phosphate process was favored.
