Abstract
CARACTERIZADO POR CONSISTIR EN: 1) DISPERSION DEL CONCENTRADO SULFIDICO DE Cu FINAMENTE DIVIDIDO EN UNA SOLUCION ACUOSA DE H2SO4 PARA FORMAR UNA PASTA Y AJUSTE DE LA CONCENTRACION DE H2SO4 PARA LOGRAR UNA CONCENTRACION PREDETERMINADA DE Cu, Fe Y ACIDO EN LA SOLUCION FINAL DE LIXIVIACION; 2) PROVEER UNA CANTIDAD EFECTIVA DE MATERIAL CARBONOSO PARTICULADO FINAMENTE DIVIDIDO PREFERIBLEMENTE CARBON (APROX. DE 3 kg A 50 kg DE CARBON/Ton DE CONCENTRADO DE SULFURO DE Cu), COMPATIBLE CON LA SOLUCION DE LIXIVIACION DE SULFATO ACIDO, LA CUAL ES OPERATIVA EN LOS PASOS DE REACCION OXIDANTE, PARA INHIBIR LA PASIVACION DE PARTICULAS DE SULFURO INCOMPLETAMENTE LIXIVIADAS; 3) AGITAR LA PASTA Y EL MATERIAL CARBONACEO, Y HACERLO REACCIONAR CON UN GAS QUE CONTENGA OXIGENO LIBRE, EN UN RECIPIENTE A PRESION (SOBREPRESION DE OXIGENO EN UN RANGO DE 100 KPa A 3000 KPa), A UNA TEMPERATURA ENTRE 90�C Y 220�C PARA PRODUCIR LA EXTRACCION SUSTANCIALMENTE COMPLETA DE LOS VALORES Cu DE DICHOS SULFUROS COMO Cu2SO4 SOLUBLE, Y LA CONVERSION CONCURRENTE DE UNA PORCION SUSTANCIAL DEL AZUFRE SULFURO ASOCIADO CON DICHOS VALORES DE Cu A AZUFRE ELEMENTAL; Y 4) SEPARAR EL RESIDUO SOLIDO DEL PRODUCTO DE LA SOLUCION DE LIXIVIACION QUE CONTIENE LOS VALORES DE Cu DISUELTOS; ES UTIL PARA EXTRAER Cu DE CONCENTRADOS SULFIDICOS, TALES COMO SULFUROS REFRACTARIOS (CALCOPIRITA)
