Abstract
DONDE EL METODO COMPRENDE: a) PROPORCIONAR UNA CORRIENTE DE ALIMENTACION QUE TIENE EL MATERIAL (MENA QUE INCLUYE Cu, Ni, Co, Zn, Pd, Pt Y Au Y Ag); b) SOMETER DICHA CORRIENTE A CONDICIONES OXIDATIVAS Y A TEMPERATURA (ENTRE 70°C Y 100°C) Y PRESION ELEVADAS DURANTE UN PERIODO ENTRE 15 MINUTOS Y 4 HORAS, EN PRESENCIA DE COMPUESTOS QUE CONTIENEN HIERRO Y/U OTROS AGENTES QUIMICOS SELECCIONADOS PARA DISMINUIR LA CONCENTRACION EFECTIVA DE ACIDO LIBRE DURANTE LA OXIDACION A PRESION Y PROMOVER LA FORMACION DE PRODUCTOS DE SULFATO DE HIERRO (III) CON pH ESTABLE, FORMANDO DE ESTE MODO UNA SUSPENSION QUE COMPRENDE: i) UNA SOLUCION DE LIXIVIACION QUE CONTIENE VALORES METALICOS Y UN RESIDUO SOLIDO CONTENIENDO PRODUCTOS DE SULFATO DE HIERRO (III); Y, ii) PRODUCTOS AMBIENTALMENTE ESTABLES DE HIERRO-ARSENICO Y HIERRO-ANTIMONIO; c) SEPARAR DICHA SOLUCION DEL RESIDUO SOLIDO; d) RECUPERAR LOS VALORES METALICOS DE LA SOLUCION SEPARADA; Y, e) RECUPERAR VALORES DE METALES PRECIOSOS DEL RESIDUO SOLIDO, MEDIANTE LIXIVIACION CON CIANURO. LAS CONDICIONES DE OXIDACION PROPORCIONAN A LA SUSPENSION: EN UNA PRIMERA PARTE DE UN RECIPIENTE, UN POTENCIAL DE REDUCCION DE OXIGENO (ORP) DE MENOS DE 425 mV, Y UNA PROPORCION MOLAR SOLUBLE FERRICA A FERROSO DE MENOS DE 1:1; Y, EN UNA SEGUNDA PARTE UN ORP DE MAS DE 425 mV Y LA PROPORCION MOLAR ES DE MAS DE 1:1; SIENDO AMBAS PARTES HASTA 50% DEL VOLUMEN TOTAL DEL RECIPIENTE. EL RECIPIENTE ES UN RECIPIENTE A PRESION (AUTOCLAVE ACCIONADA EN FORMA CONTINUA)WHERE THE METHOD INCLUDES: a) TO PROVIDE A POWER CURRENT THAT HAS THE MATERIAL (MENA THAT INCLUDES Cu, Ni, Co, Zn, Pd, Pt and Au and Ag); b) SUBMIT SUCH CURRENT TO OXIDATIVE CONDITIONS AND AT HIGH TEMPERATURE (BETWEEN 70 ° C AND 100 ° C) AND PRESSURE DURING A PERIOD BETWEEN 15 MINUTES AND 4 HOURS, IN THE PRESENCE OF COMPOUNDS CONTAINING SELECT IRON AND / OR OTHER AGENTS WITH CHEMICALS EFFECTIVE ACID FREE DURING OXIDATION UNDER PRESSURE AND PROMOTE THE FORMATION OF IRON (III) SULPHATE PRODUCTS WITH STABLE pH, IN THIS WAY FORMING A SUSPENSION THAT INCLUDES: i) A LEACHING SOLUTION CONTAINING SOLID METAL VALUES AND A RESIDUE CONTENT IRON (III) SULPHATE PRODUCTS; AND, ii) ENVIRONMENTALLY STABLE IRON-ARSENIC AND IRON-ANTIMONY PRODUCTS; c) SEPARATE SAID SOLUTION FROM SOLID WASTE; d) RECOVER THE METALLIC VALUES OF THE SEPARATED SOLUTION; AND, e) RECOVER VALUES OF PRECIOUS METALS FROM THE SOLID WASTE, THROUGH LEACHING WITH CYANIDE. THE OXIDATION CONDITIONS PROVIDE THE SUSPENSION: IN A FIRST PART OF A VESSEL, AN OXYGEN REDUCTION POTENTIAL (ORP) OF LESS THAN 425 mV, AND A SOLUBLE FERROUS TO FERROUS MOLAR RATIO OF LESS THAN 1: 1; AND, IN A SECOND PART, AN ORP OF MORE THAN 425 mV AND THE MOLAR RATIO IS MORE THAN 1: 1; BOTH PARTIES BEING UP TO 50% OF THE TOTAL VOLUME OF THE CONTAINER. THE VESSEL IS A PRESSURE VESSEL (CONTINUOUSLY DRIVEN AUTOCLAVE)
