Abstract

"PROCESSO PARA A SEPARAçãO DE PURIFICAçãO DE CRISTAIS DE SUA SUSPENSãO EM LIXìVIA". A invenção diz respeito a um método para realizar a separação de purificação de cristais fora de sua suspensão em lixívia que envolve o uso de uma coluna de lavagem com condução forçada. De acordo com a invenção, a extremidade que envolve a câmara do processo é uma parede metálica cuja superfície que se apresenta fora da câmara do processo é aquecida pelo menos ao longo do comprimento da zona de banho puro.
