Abstract
QUE COMPRENDE: a) ADHERIR ARTIFICIALMENTE EL CONCENTRADO A LA SUPERFICIE DE UN MATERIAL SOLIDO QUE LE SIRVE DE SOPORTE, EL CUAL PUEDE SER UN MATERIAL ARTIFICIAL O UNA SUSTANCIA PETREA, FORMANDO UN AGLUTINADO; b) ACOPIAR EL MATERIAL AGLUTINADO EN UNA CANCHA FORMANDO UNA PILA EN UN APILAMIENTO DE GUIJARROS; Y, c) REGAR CON UNA SOLUCION LIXIVIANTE QUE CONTIENE, AL MENOS, IONES Cl, Cu y Fe. LA ETAPA DE AGLUTINACION SE REALIZA: MEZCLANDO SIMULTANEAMENTE LOS GUIJARROS QUE TIENEN UN TAMANO MENOR QUE 3/4" CON DICHO CONCENTRADO EN UNA PROPORCION DE HASTA 20% p/p; AGREGANDO UNA SOLUCION DE CaCl2 QUE CONTIENE DE 22 g A 50 g DE Cl/L DE SOLUCION Y EN UNA PROPORCION DE 5 Kg A 250 Kg DE CaCl2/TON DE CONCENTRADO; AGREGANDO UNA SEGUNDA SOLUCION QUE CONTIENE ION SULFATO EN UNA PROPORCION DE 5 Kg A 70 Kg DE SULFATO/TON DE AGLUTINADO; Y AGREGANDO UNA CORRIENTE DE AGUA PARA QUE EL AGLUTINADO FINAL TENGA UN CONTENIDO DE HUMEDAD ENTRE 35 Kg Y 150 Kg/TON DE MATERIAL DE SOPORTE. LOS GUIJARROS ESTAN FORMADOS POR UN MINERAL O UN ESTERIL O UN DESMONTE O UNA GRAVA O UN RIPIO DE LIXIVIACION
