Abstract

Procedimiento para la obtención de carbonato de estroncio, constituido a partir de la utilización de mineral celestina (SrSO{sub,4}), efectuándose el procedimiento en cinco etapas, constitutivas de lixiviación, primera carbonatación, purificación, carbonatación final y recuperación de subproductos, así como la concentración de nitrato amónico y la cristalización de sulfato amónico, realizándose un tratamiento de las disoluciones de sulfato amónico y de nitrato amónico obtenidas para la posterior cristalización del primera y concentración del segundo.
