Abstract

METODO MEJORADO PARA EXTRAER UN METAL PRECIOSO DE LOS FINOS DE UNA MENA DE MINERAL, POR LIXIVIACION USANDO PERCOLACION EN PILA CON ACIDO SULFURICO DILUIDO, EL CUAL COMPRENDE AGLOMERAR LOS FINOS DE LA MENA EN UNA PILA CON UNA COMPOSICION DE AGENTE AGLOMERANTE, EL METODO DE AGLOMERACION COMPRENDE LA ADICION SECUENCIAL DE UN PRIMER POLIMERO SOLUBLE EN AGUA Y DESPUES DE UN SEGUNDO POLIMERO SOLUBLE EN AGUA A LOS FINOS. LOS PRIMEROS POLIMEROS PREFERIDOS SON POLI(ACRILAMIDA) Y 70/30 MOLES POR CIENTO DE POLI(ACRILAMIDA/ACRILATO DE SODIO), Y LOS SEGUNDOS POLIMEROS PREFERIDOS SON POLI(CLORURO DE DIALILDIMETILAMONIO), 90/10 MOLES POR CIENTO DE POLI(ACRILAMIDA/CLORURO DE DIALILDIMETILAMONIO) Y 99/1 MOLES POR CIENTO DE POLI(CLORURO DE DIALILDIMETILAMONIO/VINILTRIMETOXISILANO)
