Abstract

UN PROCESO PARA LA EXTRACCION DE COBRE DE UNA MINA O CONCENTRADO DE SULFATO DE COBRE, QUE COMPRENDE LOS SIGUIENTES PASOS: SOMETER LA MINA O CONCEN- TRADO A LA OXIDACION A PRESION EN LA PRESENCIA DE OXIGENO Y EN UNA SOLUCION DE ACIDO CLORHIDRICO PA- RA OBTENER UN RESULTADO DE FILTRADO DE OXIDACION A PRESION Y UNA SAL BASICA INSOLUBLE DE SULFATO DE COBRE, CARACTERIZADA EN QUE LA OXIDACION A PRESION ES REALIZADA EN PRESENCIA DE UNA FUENTE DE IONES DE BISULFATO O SULFATO QUE HA SIDO SELECCIONADA DEL GRUPO QUE CONSISTE EN ACIDO SULFURICO Y UN SULFATO METALICO QUE SE HIDROLIZA EN LA SOLUCION ACIDICA Y DONDE LA CANTIDAD DE LA FUENTE DE IONES DE BISULFATO O SULFATO QUE ES ANADIDA CONTIENE POR LO MENOS LA CANTIDAD ESTEQUIOMETRICA DE IONES DE SULFATO O BISULFATO NECESARIOS PARA PRODUCIR LA SAL BASICA DE SULFATO DE COBRE MENOS LA CANTIDAD DE SULFATO GENERADO IN SITU EN LA OXIDACION A PRE- SION. EL COBRE CUANDO HUBIERE SIDO PRODUCIDO POR EL PRO- CESO DE ACUERDO A CUALQUIERA DE LAS REIVINDICACIO- NES PRECEDENTES. UN PROCESO DE ACUERDO CON LA REIVINDICACION 21, DONDE LA MINA O EL CONCENTRADO TAMBIEN CONTIENE ZINC JUNTO CON COBRE Y COMPRENDE LAS ETAPAS DE: SOMETER LA SEGUNDA SOLUCION DE COBRE Y EL FILTRADO A OXIDACION A PRESION A LA EXTRACCION DE ZINC POR SOLVENTE, PREVIO A LA EXTRACCION DE COBRE POR SOL- VENTE CON UN EXTRACTANTE ORGANICO DE ZINC PARA PRODUCIR RESPECTIVAMENTE PRIMEROS Y SEGUNDOS EX- TRACTANTES CARGADOS DE ZINC Y RESPECTIVAMENTE PRI- MEROS Y SEGUNDOS RESIDUOS DE EXTRACCION DE ZINC. SOMETER EL PRIMER RESIDUO DE EXTRACCION DE ZINC... FIGURA 1
