Abstract
DONDE DICHO METODO COMPRENDE: a) AIREAR LA CAPA SUPERFICIAL DEL VERTEDERO, POR AGITACION O SOLTANDO MECANICAMENTE DICHA CAPA, HASTA UNA PROFUNDIDAD ENTRE 0,5 m Y 1 m; b) AJUSTAR EL pH, A UN NIVEL ENTRE 1,3 Y 2, AGREGANDO ACIDO SULFURICO, Y EL CONTENIDO DE HUMEDAD, A UN VALOR DEL ORDEN DE 18%, DE DICHA CAPA, PARA QUE LA OXIDACION BACTERIANA DE MINERALES SULFURADOS TENGA CONDICIONES FAVORABLES; c) PERMITIR QUE SE EFECTUE LA OXIDACION, DURANTE UN PERIODO CONTROLADO DE AL MENOS 4 SEMANAS; d) DESPUES DE DICHO PERIODO, REMOVER LA CAPA SUPERFICIAL OXIDADA, POR MEDIOS MECANICOS O POR EL USO DE CHORROS DE AGUA, Y AGREGARLE AGUA PARA FORMAR UNA SUSPENSION; e) SEPARAR DE LA SOLUCION, LA SUSPENSION EN SOLIDOS Y LLEVARLOS A UN ESTANQUE EN EL QUE SE AGITA; Y, f) RECUPERAR EL METAL BASE DESDE LA SOLUCION, MEDIANTE EXTRACCION POR SOLVENTES O INTERCAMBIO IONICO. EL METAL BASE PUEDE SER COBRE, Y LAS ESCORIAS PUEDEN RESULTAR DE LA MOLIENDA Y FLOTACION DE MINERALES DE COBRE
