Abstract
UN PROCEDE CONNU DE RECUPERATION DE FIBRES CELLULOSIQUES A PARTIR DE VIEUX PAPIERS CONSISTE A SEPARER UNE DISPERSION DE MATERIAUX BRUTS, PAR UNE FLOTTATION PRIMAIRE, EN UNE FRACTION RICHE EN FIBRES ET UNE FRACTION ENRICHIE EN IMPURETES HYDROPHOBES. SUIVANT L'INVENTION, ON SEPARE LA FRACTION HYDROPHOBE 7 POUR PARTIE EN UNE FRACTION RICHE EN FIBRES QUI EST RECYCLEE ET POUR PARTIE EN UNE FRACTION ENRICHIE DAVANTAGE EN IMPURETES HYDROPHOBES. ON PEUT UTILISER DES MOYENS EPURATEURS 2 QUI EMPECHENT LES FIBRES DE TRAVERSER LES FILTRES EPURATEURS ET QUI NE FORMENT PAS DE COUCHE DE FILTRAGE SUR CES FILTRES, TANDIS QUE LES IMPURETES HYDROPHOBES TRAVERSENT LES FILTRES.
