Abstract

Método de descarbonatación de diatomita mediante la utilización de ácido clorhídrico en circuito cerrado, para lo que se procede al lavado con ácido clorhídrico de las rocas de moronita con objeto de liberar la diatomita ocluida en ella, complementándose este proceso de lavado con el tratamiento de las aguas resultantes con objeto de regenerar el ácido clorhídrico y poder reutilizar las aguas en circuito cerrado.
