Abstract
Se proporciona un procedimiento para la produccion de fosfato dicalcico a partir de un material de fuente de fosfato en donde una solucion de acido fosforico se produce a traves de la accion de un acido mineral adecuado, en general el acido sulfurico, en un material de fuente de fosfato; el fluoruro de calcio se precipita a un pH de entre 3.5 y 4.5, seguido por la hidrolizacion de la solucion al diluirla con agua a una proporcion de aproximadamente 1:7 a cerca de 1:10 de fosfato monocalcico a agua, a una temperatura de aproximadamente 40°C para formar un precipitado primario que contiene substancialmente todo el fluoruro presente como CaF2 junto con una parte de fosfato dicalcico y un calcio primario y una solucion que contiene fosfato; el precipitado primario se disuelve, el pH se ajusta de 3.5 a 4.5 y la hidrolizacion se repite para formar un precipitado secundario que contiene substancialmente todo el fluoruro presente como CaF2 junto con una parte del fosfato dicalcico y un calcio secundario y una solucion que contiene fosfato; el precipitado secundario opcionalmente puede, si se requiere, a traves de procesarlo nuevamente de la misma manera, para recuperar mas fosfatos; el producto fosfato dicalcico se recupera a partir de calcio combinado y soluciones que contienen fosfato.
