Abstract

PROCEDIMIENTO PARA LA RECUPERACION HIDROMETALURGICA DE METALES NO FERREOS EN CENIZAS DE PIRITAS. PROCEDIMIENTO PARA LA RECUPERACION HIDROMETALURGICA DE METALES NO FERREOS EN CENIZAS DE PIRITAS. EL PROCEDIMIENTO COMPRENDE BASICAMENTE LAS ETAPAS DE: A) RETOSTAR PREVIAMENTE LAS CENIZAS DE PIRITAS; B) LIXIVIAR LAS CENIZAS RETOSTADAS EN CONDICIONES ACIDAS PARA RECUPERAR EL CU Y EL ZN; C) LAVAR LOS RESIDUOS LIXIVIADOS; D) PREAIREAR Y ALCALINIZAR DICHO RESIDUO, E) CIANURAR EL RESIDUO DE LA ETAPA D); LA RETOSTACION PUEDE EFECTUARSE CON O SIN ADICION DE PIRITA A UNA TA DE 500-600GC DURANTE 0,5-24 HORAS. SEGUN ESTE PROCEDIMIENTO SE PUEDEN REALIZAR EXTRACCIONES DE CU Y ZN DEL 80-90%, DE AU DEL 80-85%, Y DE APROXIMADAMENTE EL 50% DE AG. ADICIONALMENTE SE EVITAN LAS REPRECIPITACIONES DE AU Y AG Y SE REDUCE EL CONSUMO DE NACN EN LA CIANURACION. ESTE PROCEDIMIENTO ES ADECUADO PARA EL BENEFICIO EN LAS CENIZAS DE PIRITA COMO MENA DE CU, ZN, AG, Y AU.PROCEDURE FOR THE HYDROMETALLURGICAL RECOVERY OF NON-IRON METALS IN ASHES OF PIRITAS. PROCEDURE FOR THE HYDROMETALLURGICAL RECOVERY OF NON-IRON METALS IN ASHES OF PIRITAS. THE PROCEDURE BASICALLY UNDERSTANDS THE STAGES OF: A) PRE-RETURNING THE ASHES OF PIRITAS; B) LEACHING ASHES RETURNED UNDER ACIDIC CONDITIONS TO RECOVER CU AND ZN; C) WASHING LEACHED WASTE; D) PRE-AIR AND ALKALIZE SUCH WASTE, E) CYANURATE WASTE FROM STAGE D); RETOSTATION CAN BE CARRIED OUT WITH OR WITHOUT ADDITION OF PIRITE AT A TA OF 500-600GC FOR 0.5-24 HOURS. ACCORDING TO THIS PROCEDURE, EXTRACTIONS OF CU AND ZN OF 80-90%, OF AU OF 80-85%, AND OF APPROXIMATELY 50% OF AG. ADDITIONALLY THE REPRECIPITATIONS OF AU AND AG ARE AVOIDED AND THE CONSUMPTION OF NACN IN THE CYANURATION IS REDUCED. THIS PROCEDURE IS SUITABLE FOR THE BENEFIT IN PIRITA ASHES AS MENA DE CU, ZN, AG, AND AU.
