Abstract

<B>PURIFICAçãO DE HIDRóXIDO DE CáLCIO ALTAMENTE IMPURO E PRODUçãO DE CARBONATO DE CáLCIO PRECIPITADO DE ALTO-VALOR E OUTROS PRODUTOS DE CáLCIO<D>, onde uma solução para um processo para a purificação de hidróxido de cálcio, particularmente a partir de carbureto de cal hidratado, o qual é subseq³entemente usado como suprimento de alimentação para produto de cálcio de alto valor, preferencialmente carbonato de cálcio. O carbonato de cálcio é formado através da reação da solução de hidróxido de cálcio purificado com dióxido de carbono em um sistema de reação de fluxo conectado.
