Abstract

A.LE PROCEDE EST DESTINE A MESURER EN CONTINU LA TENEUR DE PULPES DE FLOTTATION EN CERTAINS ELEMENTS PAR UN PROCEDE D'ANALYSE PAR FLUORESCENCE AUX RAYONSX. B.L'ECHANTILLON A MESURER PASSE ENTRE UNE SOURCE D'EXCITATION ET UN DETECTEUR, UNE CIBLE EXCITEE PAR LA SOURCE DONNANT UN RAYONNEMENT APPROPRIE QUI TRAVERSE L'ECHANTILLON COMME LE RAYONNEMENT PRIMAIRE, LE SPECTRE DES DIFFERENTS RAYONNEMENTS ETANT UTILISE APRES RECEPTION PAR LE DETECTEUR POUR DETERMINER DIRECTEMENT LA TENEUR EN ELEMENTS. C.CE PROCEDE PERMET, AVEC LE DISPOSITIF, UNE DETERMINATION TRES RAPIDE ET CONTINUE DES TENEURS INDEPENDAMMENT DE LA MASSE VOLUMIQUE ET DE LA COMPOSITION DE LA PULPE.
