Abstract
DONDE DICHO PROCESO SE LLEVA A CABO A UNA TEMPERATURA INICIAL DE 50°C, Y COMPRENDE: i) TRITURAR EL MATERIAL, A UN TAMANO DE PARTICULA MENOR A 40 MICRONES; Y, ii) TRATAR EL MATERIAL TRITURADO, CON UNA SOLUCION ALCALINA ACUOSA QUE TIENE UN pH ENTRE 8 Y 16, MEDIANTE AGITACION, Y QUE CONTIENE: a) UN AGENTE DE OXIDACION, DE PREFERENCIA GAS OXIDANTE, INTRODUCIDO POR MEDIO DE BURBUJEO A TRAVES DE LA SOLUCION, A UNA VELOCIDAD DE 0,1 l/h POR LITRO DE SOLUCION SI EL GAS OXIDANTE ES OXIGENO, O DESDE 1 l/h HASTA 350 l/h POR LITRO DE SOLUCION SI EL GAS OXIDANTE ES AIRE; Y, b) COMPLEJOS DE IONES DE UNO O MAS ELEMENTOS DE TRANSICION DE CONCENTRACION ENTRE 0,5 g/l Y 1,5 g/l, DE PREFERENCIA Cu, Ni, Zn o Co, CON AMONIACO. EL METAL PUEDE SER Cu, Pb, Fe, Co, Ag, Au, Sb, As o Ba. SI EL MATERIAL ES CALCOPIRITA, SE DISMINUYE EL pH DE LA SOLUCION Y COMPUESTO DE Cu Y Fe PRECIPITAN FUERA DE LA SOLUCION, SEPARANDO MAGNETICAMENTE EL COMPUESTO DE FeWHERE SAID PROCESS IS CARRIED OUT AT AN INITIAL TEMPERATURE OF 50 ° C, AND INCLUDES: i) CRUSHING THE MATERIAL, TO A PARTICLE SIZE LESS THAN 40 MICRONS; AND, ii) TREAT THE CRUSHED MATERIAL, WITH AN AQUEOUS ALKALINE SOLUTION THAT HAS A pH BETWEEN 8 AND 16, THROUGH AGITATION, AND THAT CONTAINS: a) AN OXIDATION AGENT, PREFERABLY OXIDIZING GAS, INTRODUCED THROUGH A BUBBLE THROUGH THE SOLUTION, AT A SPEED OF 0.1 l / h PER LITER OF SOLUTION IF THE OXIDIZING GAS IS OXYGEN, OR FROM 1 l / h TO 350 l / h PER LITER OF SOLUTION IF THE OXIDIZING GAS IS AIR; AND, b) ION COMPLEXES OF ONE OR MORE CONCENTRATION TRANSITION ELEMENTS BETWEEN 0.5 g / l AND 1.5 g / l, PREFERENCE Cu, Ni, Zn or Co, WITH AMMONIA. THE METAL CAN BE Cu, Pb, Fe, Co, Ag, Au, Sb, As or Ba. IF THE MATERIAL IS CHALCOPYRITE, THE pH OF THE SOLUTION IS REDUCED AND THE CU AND FE COMPOUND PRECIPITES OUT OF THE SOLUTION, MAGNETICALLY SEPARATING THE Fe COMPOUND
