Abstract

"PROCESSO DE PREPARAçãO DE FOSFATOS DE BASES FORTES". A presente invenção refere-se a um processo de preparação de fosfatos de bases fortes, que compreende uma formação de uma polpa constituída por uma fase aquosa que contém fosfato de cálcio solúvel na água, e por uma fase sólida que contém impurezas, uma separação entre essas fases, um deslocamento na fase líquida dos íons cálcio por íons de uma base forte com formação de uma solução aquosa de fosfato(s) puro(s) da dita base forte e precipitação de um fosfato de cálcio puro insolúvel na água, processo no qual mistura-se minério e ácido fosfórico de modo a obter uma composição pastosa de triplo superfosfato à qual adiciona-se água para obter a dita polpa.
