DESPUES DE (c) LA RELACION DE OXIDOS DE METAL A SULFATOS DE METAL ESTA ENTRE 0,3:1 Y 8:1 Y UN CONTENIDO DE SULFURO QUE OSCILA ENTRE 1% Y 0,5% EN PESO. LA TEMPERATURA MAXIMA DEL LECHO DEL MATERIAL QUE CONTIENE SULFUROS Y DE LOS SULFUROS DE METAL SELECCIONADO NO ES MAYOR DE 690°C. EL METAL SELECCIONADO ES AL MENOS UNO DE Cu, Ni, Co Y Mn. DESPUES DE (c) EL MATERIAL: i)COMPRENDE NO MAS DE 5% EN PESO DE FERRITAS DE METAL Y LA MAYORIA DEL METAL EN EL MATERIAL OXIDADO SE ENCUENTRA EN FORMA DE SULFATO; Y, ii)TIENE UN CONTENIDO MAXIMO DE SULFURO NO MAYOR DE 1% EN PESO Y LA MAYORIA DEL METAL EN EL MATERIAL OXIDADO SE ENCUENTRA EN LA FORMA XO, DONDE X ES EL METAL. LA FUENTE DE ENERGIA MICROONDAS TIENE UN NIVEL DE POTENCIA ENTRE 1 KW Y 150 KW POR UNIDAD GENERADORA Y OPERA EN UNA FRECUENCIA ENTRE 300 MHz Y 3 GHz, ESTANDO LA ENERGIA DISTRIBUIDA ENTRE 250 J/gm Y 300 000 J/gmWHERE THE PROCESS INCLUDES: a) PASSING MICROWAVE ENERGY THROUGH A BED OF MATERIAL CONTAINING SULFIDES, WHILE THE MATERIAL IS PLACED IN A FLUIDIZED BED REACTOR; b) DURING (a), PASSING A FLUIDIZING GAS THROUGH THE REACTOR, TO OXIDIZE THE METAL SULFIDES IN THE MATERIAL AND FORM A MATERIAL CONTAINING OXIDIZED METAL; AND, c) REMOVE THE MATERIAL FROM THE REACTOR, WHERE THE FLUIDIZED BED IS PLACED ON AN INERT BED OF PARTICULATED MATERIAL WHERE THE MATERIAL HAS A P80 SIZE BETWEEN 35 AND 75 MICRONS AND THE PARTICULATED MATERIAL IN THE INERT BED AND HAS A P80 SIZE 200 300 MICRONS. AFTER (c) THE RATIO OF METAL OXIDES TO METAL SULPHATES IS BETWEEN 0.3: 1 AND 8: 1 AND A SULFIDE CONTENT THAT RANGES BETWEEN 1% AND 0.5% BY WEIGHT. THE MAXIMUM BED TEMPERATURE OF THE MATERIAL CONTAINING SULFIDES AND THE SELECTED METAL SULFIDES IS NOT HIGHER THAN 690 ° C. THE SELECTED METAL IS AT LEAST ONE OF Cu, Ni, Co AND Mn. AFTER (c) THE MATERIAL: i) INCLUDES NO MORE THAN 5% BY WEIGHT OF METAL FERRITES AND MOST OF THE METAL IN THE RUSTY MATERIAL IS IN THE FORM OF SULPHATE; AND, ii) IT HAS A MAXIMUM SULFIDE CONTENT OF NO GREATER THAN 1% BY WEIGHT AND MOST OF THE METAL IN THE RUSTY MATERIAL IS IN THE XO FORM, WHERE X IS THE METAL. THE MICROWAVE ENERGY SOURCE HAS A POWER LEVEL BETWEEN 1 KW AND 150 KW PER GENERATOR UNIT AND OPERATES AT A FREQUENCY BETWEEN 300 MHz AND 3 GHz, WITH THE ENERGY DISTRIBUTED BETWEEN 250 J / gm AND 300,000 J / gm
