Abstract

L'INVENTION CONCERNE LA SEPARATION DES MATERIAUX SUIVANT LEURS PROPRIETES ELECTROMAGNETIQUES. CETTE SEPARATION EST EFFECTUEE EN AMENANT UN COURANT DE MATERIAU DANS LA ZONE D'INTENSITE MAXIMUM D'UN CHAMP MAGNETIQUE ALTERNATIF HETEROGENE POUR INDUIRE, DANS LES PARTICULES CONDUCTRICES D'ELECTRICITE DE CE MATERIAU, DES COURANTS TOURBILLONNAIRES MAXIMUM ET CREER DES FORCES ELECTROMAGNETIQUES MAXIMUM FAISANT DEVIER LES PARTICULES CONDUCTRICES HORS DE LEUR TRAJET INITIAL. LE CHAMP MAGNETIQUE ALTERNATIF HETEROGENE EST ENGENDRE PAR UN ELECTRO-AIMANT 1 DONT LE CIRCUIT MAGNETIQUE EST FERME DANS UN ENTREFER FORME PAR LES EPANOUISSEMENTS POLAIRES 2. LES EPANOUISSEMENTS POLAIRES 2 DIVERGENT SYMETRIQUEMENT A PARTIR DES AXES DES POLES DANS UN PLAN PRATIQUEMENT PERPENDICULAIRE AU SENS DE L'ECOULEMENT DU MATERIAU A SEPARER. APPLICATION: GEOLOGIE, ENTREPRISES D'ENRICHISSEMENT LORS DU TRAITEMENT DES CONCENTRES AURIFERES, OU SEPARATION DES METAUX NON FERREUX SECONDAIRES ET TRAITEMENT DES DECHETS.
