Abstract
UN PROCESO PARA LA EXTRACCION DE COBRE DE UN MINERAL O CONCENTRADO DE COBRE AL SULFURO QUE CONSISTEN EN SOMETER AL MINERAL O CONCENTRADO A UNA OXIDACION A PRESION EN PRESENCIA DE OXIGENO Y DE UNA SOLUCION DE CLORURO ACIDICA PARA OBTENER UN FILTRADO DE LA OXIDACION A PRESION Y UNA SAL DE SULFATO DE COBRE BASICA INSOLUBLE. LA OXIDACION A PRESION SE LLEVA A CABO EN PRESENCIA DE UNA FUENTE DE IONES DE BISULFATO O SULFATO, TAL COMO UN ACIDO SULFURICO. LA CANTIDAD DE LA FUENTE DE SULFATO AÑADIDA CONTIENE AL MENOS UNA CANTIDAD ESTOIQUIOMETRICA DE IONES DE SULFATO NECESARIOS PARA LA PRODUCCION DE LA SAL DE SULFATO DE COBRE BASICA MENOS LA CANTIDAD DEL SULFATO GENERADO IN SITU EN LA OXIDACION A PRESION. EN UN ASPECTO PARTICULAR DE LA INVENCION, LA OXIDACION A PRESION SE LLEVA A CABO SEGUN UNA RELACION PREDETERMINADA DE H{SUP,+}/CU DE MODO QUE EL FILTRADO LA DE OXIDACION A PRESION CONTENGA UNA PORCION PRINCIPAL DEL COBRE DEL MINERAL O CONCENTRADO Y LA SAL DE COBRE BASICA CONTENGA UNA PORCION MENOR DEL COBRE DEL CONCENTRADO. EN LA INVENCION TAMBIEN SE PRESENTA LA SELECCION DE LA RELACION DE H{SUP,+}/CU SEGUN EL GRADO DEL MINERAL O CONCENTRADO, EN DONDE EL VALOR DE LA RELACION SE SELECCIONA CON UNA MAGNITUD EN AUMENTO EN COMPARACION A UN GRADO EN DESCENSO DEL MINERAL O CONCENTRADO. EN OTRO ASPECTO DE LA INVENCION, LA SAL DE COBRE BASICA SE DISUELVE EN UNA ETAPA DE LIXIVIACION ATMOSFERICA SUBSIGUIENTE. AL EXTRAER EL SOLVENTE SE OBTIENE UNA SOLUCION DE COBRE CONCENTRADA, ADECUADA PARA UNA EXTRACCION ELECTROLITICA. EL PROCESO TAMBIEN CONSISTE EN LA EXTRACCION DEL ZINC Y DEL NIQUEL DEL MINERAL.
