Abstract

DONDE EL PROCEDIMIENTO COMPRENDE: a) TRANSFORMACION DE LAS MENAS O CONCENTRADOS DE MENAS, MEDIANTE REACCION EN ATMOSFERA INERTE CON AZUFRE DE 300°C A 600°C DURANTE UN TIEMPO ENTRE 5 MINUTOS Y 24 HORAS; b) MOLIENDA DEL PRODUCTO DE REACCION; c) SEPARACION FISICA AL MENOS PARCIAL DE LOS SULFUROS QUE CONTIENEN COBRE OBTENIDOS DE LOS SULFUROS DE HIERRO, MEDIANTE PROCEDIMIENTOS ELECTROSTATICOS, GRAVIMETRICOS O MAGNETICOS, SEPARACION POR AIRE, SELECCION DE TAMANOS DE PARTICULA, Y PROCEDIMIENTOS CON HIDROCICLON O DE FLOTACION; Y, d) TRATAMIENTO DE LOS SULFUROS QUE CONTIENEN COBRE SEPARADOS, MEDIANTE PROCEDIMIENTOS PIROMETALURGICOS O HIDROMETALURGICOS PARA OBTENER COBRE. (a) ES CONTINUA, EN UN SISTEMA DE TRES CAMARAS, Y SE LLEVA A CABO EN UN HORNO ROTATIVO TUBULAR O REACTOR DE LECHO FLUIDIZADO. (b) SE REALIZA AL MENOS PARCIALMENTE EN EL HORNO ROTATIVO TUBULAR O REACTOR DE LECHO FLUIDIZADO IN SITU MEDIANTE INCORPORACION DE BOLAS DE MOLIENDA. EL AZUFRE SE ANADE ESTEQUIOMETRICAMENTE, SEMIESTEQUIOMETRICAMENTE O CATALITICAMENTE. DURANTE (a) SE REALIZA UN ENRIQUECIMIENTO DE METALES PRECIOSOS EN LA FASE DE SULFURO DE COBRE. LAS MENAS O CONCENTRADOS DE MENAS SE SELECCIONAN DE CALCOPIRITA (CuFeS2), BORNITA (Cu5FeS4), CUBANITA (CuFeS4), CALCOSINA (Cu2S), DIGENITA (Cu9S5) Y/O COVELINA (CuS). LOS SULFUROS DE HIERRO SON PIRITA O PIRROTINAWHERE THE PROCEDURE INCLUDES: a) TRANSFORMATION OF MINES OR CONCENTRATES OF MINES, BY REACTION IN AN INERT ATMOSPHERE WITH SULFUR FROM 300 ° C TO 600 ° C DURING A TIME BETWEEN 5 MINUTES AND 24 HOURS; b) GRINDING THE REACTION PRODUCT; c) PHYSICAL SEPARATION AT LEAST PARTIAL OF THE SULFIDES CONTAINING COPPER OBTAINED FROM IRON SULFIDES, THROUGH ELECTROSTATIC, GRAVIMETRIC OR MAGNETIC PROCEDURES, SEPARATION BY AIR, SELECTION OF PARTICULATE SIZES, OR FLUIDING PROCEDURES; AND, d) TREATMENT OF THE SULFIDES CONTAINING SEPARATED COPPER, THROUGH PYROMETALLURGICAL OR HYDROMETALLURGICAL PROCEDURES TO OBTAIN COPPER. (a) IT IS CONTINUOUS, IN A THREE-CHAMBER SYSTEM, AND CARRIED OUT IN A TUBULAR ROTARY OVEN OR FLUIDIZED BED REACTOR. (b) IT IS PERFORMED AT LEAST PARTIALLY IN THE TUBULAR ROTARY FURNACE OR FLUIDIZED BED REACTOR ON SITU BY INCORPORATION OF GRINDING BALLS. SULFUR IS ADDED STECHOMETRICALLY, SEMIESTECHIOMETRICALLY OR CATALYTICALLY. DURING (a) PRECIOUS METALS ENRICHMENT IS CARRIED OUT IN THE COPPER SULFIDE PHASE. THE MINES OR CONCENTRATES OF MINES ARE SELECTED FROM CHALCOPYRITE (CuFeS2), BORNITE (Cu5FeS4), CUBANITE (CuFeS4), CALCOSINE (Cu2S), DIGENITE (Cu9S5) AND / OR COVELIN (CuS). IRON SULFIDES ARE PYRITE OR PYROTHIN
