Abstract

METODO Y APARATO PARA EL BENEFICIO DE MINERALES POR EL METODO DE FLOTACION, DE ACUERDO CON LOS CUALES SE INTRODUCE A PRESION UN LODO EN LA PARTE SUPERIOR (1) DE UNA PRIMERA COLUMNA (2) A TRAVES DE UNA BOQUILLA (3) DIRIGIDA HACIA ABAJO Y SE HACE CIRCULAR AIRE EN EL LODO PARA FORMAR UN LECHO DE ESPUMA QUE SE MUEVE HACIA ABAJO EN LA PRIMERA COLUMNA. DICHO LECHO DE ESPUMA PASA DEL FONDO (12) DE LA PRIMERA COLUMNA A LA SEGUNDA COLUMNA (5), DONDE ESPUMA Y LIQUIDO SE SEPARAN, LLEVANDO LA PRIMERA (16) EL MINERAL, FLOTANDO HACIA ARRIBA A UN REBOSADERO (15), MIENTRAS QUE EL LIQUIDO SE DESCARGA CON LA GANGA. EL NIVEL DE LA ZONA DE CONTACTO (7) LIQUIDO/ESPUMA EN LA SEGUNDA COLUMNA, SE MANTIENE POR ENCIMA DEL FONDO DE LA PRIMERA COLUMNA, Y LA VELOCIDAD DE CIRCULACION DEL AIRE EN LA PARTE SUPERIOR DE ESTA ESTA CONTROLADA PARA MANTENER ESTA COLUMNA (2) LLENA DE ESPUMA.
