Abstract
"PROCESSO PARA PRODUçãO DE FOSFATO DICáLCICO OU FOSFATO DE MONOCáLCIO". Apresenta-se um processo para a produção de fosfato dicálcico a partir de um material de fonte fosfática no qual uma solução de ácido fosfórico é produzida através da ação de um ácido mineral adequado, geralmente ácido sulfúrico, em um material de fonte fosfática. Fluoreto de cálcio é precipitado em um pH entre 3,5 e 4,5 seguido por hidrólise da solução através de sua diluição com água até uma proporção de cerca de 1:7 até cerca de 1:10 entre fosfato de monocálcio e água numa temperatura de aproximadamente 40<198>C para formar um precipitado primário contendo essencialmente a totalidade do fluoreto presente como CaF~ 2~ juntamente com algum fosfato dicálcico e uma solução primária contendo cálcio e fosfato. O precipitado primário é dissolvido, o pH ajustado para 3,5 a 4,5 e a hidrólise é repetida para formar um segundo precipitado um precipitado secundário contendo essencialmente a totalidade do fluoreto presente como CaF~ 2~ juntamente com algum fosfato dicálcico e uma solução secundária contendo cálcio e fosfato. O precipitado secundário pode opcionalmente, caso necessário, ser novamente processado da mesma maneira para recuperar mais fosfatos. O produto de fosfato dicálcico é recuperado a partir das soluções combinadas contendo cálcio e fosfato.
