Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA PURIFICACION DE UNA MEZCLA DE CLORURO DE SODIO. MEDIANTE LA COMBINACION DE LIXIVIACION Y FLOTACION SE PREPARA, CON EMPLEO DE UN AMPLIO ESPECTRO DE SOLUCIONES DE TRATAMIENTO, UN PRODUCTO DE NACL MUY VALIOSO CON UNA PUREZA SUPERIOR A 99%. EL PROCESO DE PURIFICACION SE LLEVA A CABO EN UN RECIPIENTE DE REACCION CONICO QUE ESTA PROVISTO DE UN TUBO DE EXTRACCION VERTICAL Y VARIABLE EN ALTURA. ESTE TUBO DE EXTRACCION SIRVE SIMULTANEAMENTE PARA LA OBTENCION DE PRODUCTO, LA CLASIFICACION Y LA FLOTACION, MIENTRAS QUE AL RECIPIENTE DE REACCION PRINCIPAL ESTA ASOCIADO EL PROCESO DE LIXIVIACION Y LA ZONA DE SEDIMENTACION PARA LA SEPARACION DE LAS IMPUREZAS. (FIGURA UNICA).
