Abstract

SE REFIERE A UN METODO DE FLOTACION CON ESPUMA PARA CONCENTRAR MINERALES DE UN MATERIAL DE GRANO GRUESO, EN CUYO METODO: A)SE FORMA UNA SUSPENSION ESPESA DEL MATERIAL DE GRANO GRUESO Y PRODUCTOS QUIMICOS DE FLOTACION; B)LA SUSPENSION ES PREPARADA SIN PRODUCIR SEDIMENTO; C)SE PROVEE UNA FASE LIQUIDA Y SE DISPONE UNA FASE DE ESPUMA EN LA SUPERFICIE DE LA FASE LIQUIDA; Y, D)LA SUSPENSION ES ALIMENTADA EN LA FASE DE ESPUMA , CON EL RESULTADO DE QUE LAS PARTICULAS HIDROFOBAS SON CAPTURADAS EN LA ESPUMA, PARA SER RETIRADAS EN FORMA DE UN FLUJO SUPERIOR, MIENTRAS QUE LAS PARTICULAS HIDROFILAS SE HUNDEN A TRAVES DE LA ESPUMA EN LA FASE LIQUIDA DEBAJO DE ESTA PARA SER RETIRADAS EN FORMA DE UN FLUJO INFERIOR; CARACTERIZADO PORQUE EN LA FASE DE PREPARACION DEL METODO LA SUSPENSION SE SOMETE A MOVIMIENTO DE FLUJO CON UN MODELO DE FLUJO AXIAL DE CIRCULACION VERTICAL. ADEMAS DE UN APARATO DE FLOTACION QUE COMPRENDE UN PREPARADOR, UN SEPARADOR DE FLOTACION, UN MEDIO DE ALIMENTACION, UN PRIMER MEDIO DE REMOCION Y UN SEGUNDO MEDIO DE REMOCION CARACTERIZADO PORQUE EL PREPARADOR ES UNA MEZCLADORA DE ROTOR HELICOIDALIT REFERS TO A FOAM FLOATING METHOD TO CONCENTRATE MINERALS FROM A COARSE GRAIN MATERIAL, IN WHICH METHOD: A) A THICK SUSPENSION OF THE COARSE GRAIN MATERIAL AND FLOTATION CHEMICALS IS FORMED; B) THE SUSPENSION IS PREPARED WITHOUT PRODUCING SEDIMENT; C) A LIQUID PHASE IS PROVIDED AND A FOAM PHASE IS DISPOSED ON THE SURFACE OF THE LIQUID PHASE; AND, D) THE SUSPENSION IS SUPPLIED IN THE FOAM PHASE, WITH THE RESULT THAT THE HYDROPHOBIC PARTICLES ARE CAPTURED IN THE FOAM, TO BE REMOVED IN THE FORM OF A SUPERIOR FLOW, WHILE THE HYDROPHILIC PARTICLES SINK THROUGH THE FOAM IN THE LIQUID PHASE BELOW IT TO BE WITHDRAWN IN THE FORM OF A LOWER FLOW; CHARACTERIZED BECAUSE IN THE PREPARATION PHASE OF THE METHOD THE SUSPENSION IS SUBJECTED TO FLOW MOVEMENT WITH A VERTICAL CIRCULATION AXIAL FLOW MODEL. IN ADDITION TO A FLOTATION APPARATUS INCLUDING A PREPARATOR, A FLOTATION SEPARATOR, A FEEDING MEANS, A FIRST REMOVAL MEANS AND A SECOND REMOVAL MEANS CHARACTERIZED BECAUSE THE PREPARER IS A HELICAL ROTOR MIXER
