Abstract
UN SENCILLO, EFICIENTE Y BARATO METODO DE PURIFICAR SULFATO MAGNESICO A PARTIR DE MEZCLAS DE EPSOMITA Y HALITA. EL METODO PERMITE LA PREPARACION DE PRODUCTOS DE SULFATO MAGNESICO SUSTANCIALMENTE PURO. EL METODO INCLUYE GENERALMENTE CALENTAR UNA MEZCLA DE EPSOMITA Y HALITA PARA FORMAR AGLOMERACIONES DE CRISTALES DE SULFATO DE MAGNESIO HIDRATADO INFERIORES Y APLICAR SUBSECUENTEMENTE LEVE PRESION A LAS AGLOMERACIONES DE MODO QUE COLAPSEN PARA PRODUCIR FINOS CRISTALES DE SULFATO MAGNESICO INFERIOR HIDRATADO QUE PUEDE ENTONCES SER FACILMENTE SEPARADO DE LOS CRISTALES DE HALITA COMPARATIVAMENTE BASTOS. LOS CRISTALES DE SULFATO MAGNESICO INFERIOR HIDRATADO PUEDEN SER RECRISTALIZADOS PARA PROPORCIONAR EPSOMITA ALTAMENTE PURIFICADA QUE PUEDE SER DESHIDRATADA PARA PROPORCIONAR KIESERITA O SULFATO MAGNESICO ANHIDRO.
