Abstract

PROCEDIMIENTO DE RECUPERACION DE ORO A PARTIR DE MINERALES REFRACTARIOS. CONSISTE EN SOMETER LOS MINERALES DE ORO REFRACTARIOS A OXIDACION A PRESION EN AUTOCLAVE, CON OXIGENO U OTROS OXIDANTES. SE OBTIENE UNA LECHADA OXIDADA POR DISGRAGACION DE LOS MINERALES EN PULPAS DE OXIDACION MUY FINAS, QUE ES TRATADA PARA ELIMINAR DE ELLA, LOS METALES PESADOS Y LOS SULFATOS, YA QUE OXIDADOS ACTUARIAN COMO CIANICIDAS; EL TRATAMIENTO SE LLEVA A CABO MEDIANTE LAVADO Y CLARIFICACION CON UN DILUYENTE ACUOSO. LA LECHADA LAVADA Y A UN PH DE 10,5 A 11, SE SOMETE A CINAURACION EN AGITACION Y AIREACION CONTINUAS, MEDIANTE UNA SAL CIANURO A UNA CONCENTRACION FINAL DE APROXIMADAMENTE 0,5 KG POR TONELADA DE LECHADA. POSTERIORMENTE EL PRODUCTO ES LLEVADO A RECUPERACION POR CABON EN PULPA, PRODUCIENDOSE LA EXTRACCION DEL ION AUROCIANURO SOLUBLE DE LA PULPA; UTILIZANDO PARA ESTA FASE CABON DE COCO. DE UTILIZACION PARA RECUPERAR EL ORO DE MINERALES REFRACTARIOS.
