Abstract

QUE COMPRENDE: a) DISPERSAR UN CONCENTRADO QUE CONTIENE SULFURO DE COBRE FINAMENTE DIVIDIDO, CON UN TAMANO DE PARTICULA ENTRE 5 µm Y 20 µm, EN UNA SOLUCION DE ACIDO SULFURICO PARA FORMAR UNA SUSPENSION, DONDE LA CANTIDAD DE ACIDO ES DADA POR LA CONCENTRACION DE COBRE, HIERRO Y ACIDO EN LA SOLUCION DE LIXIVIACION FINAL; b) PROPORCIONAR UN SURFACTANTE APROPIADO, TAL COMO DERIVADOS DE LIGNINA, ORTOFENILENO AMINA, SULFONATOS DE ALCARILO Y MEZCLA DE LOS MISMOS, EN UNA CANTIDAD EFECTIVA ENTRE 2 Kg Y 5 Kg POR TONELADA DE CONCENTRADO; c) HACER REACCIONAR LA SUSPENSION Y EL SURFACTANTE, POR AGITACION CON GAS CONTENIENDO OXIGENO LIBRE A UNA SOBREPRESION DE OXIGENO ENTRE 100KPa Y 3000 KPa, EN UN RECIPIENTE A PRESION A UNA TEMPERATURA ENTRE 130°C Y 160°C, PARA EXTRAER LAS RIQUEZAS DE COBRE DESDE EL CONCENTRADO, Y PARA FORMAR UNA SOLUCION DE LIXIVIACION FINAL CONTENIENDO VALORES DE COBRE DISUELTOS Y UN RESIDUO SOLIDO; Y, d) SEPARAR LA SOLUCION DE LIXIVIACION FINAL, DEL RESIDUO SOLIDO. DICHO CONCENTRADO CONTIENE CALCOPIRITA, Y ES DE PREFERENCIA CALCOCITA, BORNITA, ENERGITA Y TETRAHEDRITA
