Abstract

METODO DE DESAGUAR SUSPENSIONES DE MINERALES. CONSISTE EN TRATAR LAS SUSPENSIONES CON SUSTANCIAS DE ACTIVIDAD SUPERFICIAL EN UNA CANTIDAD DE 0,03 A 2%. DICHAS SUSTANCIAS DE ACTIVIDAD SUPERFICIAL, TIENEN UN NUMERO DE HLB DE 8 A 12 O UN NUMERO DE H/L DE 50 A 150%, DESPUES DE ESTO, LA SUSPENSION SE DESAGUA, ANTES DE LO CUAL SE AÑADE UN POLIELECTROLITO POLIMERICO LINEAL IONICO O NO IONICO DE CARACTER CATIONICO, TENIENDO DICHOS POLIELECTROLITOS, EN AMBOS CASOS UN PESO MOLECULAR DE 500.000 O MAYOR. LA SOLUCION SE DESAGUA EN UNA CAMARA DE FILTRO O EN UN DEPOSITO DE SEDIMENTACION.
