Abstract

PROCESO DE OBTENCION DE SALES FERTILIZANTES Y DERIVADOS DE ESTRONCIO, POR VIA HUMEDA, PARTIENDO DE MINERAL EN FORMA DE SULFATO DE ESTRONCIO, AL CUAL SE LE HACE REACCIONAR CON EXCESO DE CARBONATO AMONICO. ESTA REACCION SE EFECTUA EN FORMA CONTINUA Y CON FLUJOS DE REACTIVOS EN CONTRACORRIENTE. EL EXCESO DE CARBONATO AMONICO UTILIZADO, SE RECUPERA PARA REINTEGRARLO NUEVAMENTE EN EL PROCESO Y DEJAR AISLADO EL SULFATO AMONICO QUE SE PUEDE TRATAR EN REGIMEN CONTINUO CON CARBONATO U OXIDO DE CAL, RECUPERANDO LOS GASES DESPRENDIDOS EN LA REACCION Y OBTENIENDO COMO PRODUCTO FINAL SULFATO DE CAL (YESO). EN UNA SEGUNDA FASE SE HACE REACCIONAR EN CONTINUO EL CARBONATO DE ESTRONCIO OBTENIDO CON ACIDO NITRICO PARA OBTENER NITRATO DE ESTRONCIO, PARTE DEL CUAL SE CARBONATA CON GASES (COSI2 Y NHSI3) DANDO LUGAR A UN CARBONATO DE ESTRONCIO PRECIPITADO Y UNA SOLUCION DE NITRATO AMONICO.
