Abstract

LA INVENCION SE REFIERE A UN PROCESO DE TRATAMIENTO DE PAPEL VIEJO CON UNA FLOTACION SELECTIVA, DONDE SE CONSIGUE UNA FLOTACION SELECTIVA MULTIPLE. LA INVENCION SE CARACTERIZA PORQUE, LA ESPUMA TANGENCIAL SE GUIA A UN HIDROCICLON, QUE GENERA DOS FRACCIONES. LAS PARTICULAS LIGERAS A PARTIR DEL NUCLEO Y EL GAS CORRESPONDIENTE EN EL EXTREMO SUPERIOR Y LAS SUCIEDADES SE LLEVAN AL EXTREMO INFERIOR, Y SE RECHAZA LA FRACCION INFERIOR ANTES DE LA INSTALACION DE FLOTACION SELECTIVA Y LA FRACCION DE NUCLEO.
