Abstract

Un método para la fabricación de hidrogenofosfato cálcico a partir de fosfato cálcico, que comprende:**(Fórmula)** (1) hacer reaccionar el fosfato cálcico con un ácido mineral adecuado para formar la sal cálcica correspondiente y ácido fosfórico; (2) descomponer o hacer reaccionar la sal cálcica de la etapa (1) con agua o un hidróxido de metal alcalino para formar óxido cálcico o hidróxido cálcico y el ácido mineral de la etapa (1), o su sal; (3) cuando se forma la sal del ácido mineral en la etapa (2), electrolizar tal sal para formar el ácido mineral correspondiente junto con un álcali; (4) reciclar el ácido mineral de la etapa (2) o (3) a la etapa (1); y (5) hacer reaccionar el óxido cálcico o el hidróxido cálcico de la etapa (2) con el ácido fosfórico de la etapa (1) para formar hidrogenofosfato cálcico.
