Abstract

Un método de purificar materiales separando materia sólida sin disolver a partir de una mezcla de la misma con un líquido que contiene también materia sólida deseada en solución, caracterizado porque se hace pasar el líquido impuro a través de un filtro que contiene un lecho de arena que dejará pasar la solución de materia sólida pero retendrá la materia sólida sin disolver, se rastrilla la superficie del lecho de arena para romper cualquier torta que se forme allí, y se recoge el filtrado que pasa por el filtro.
