Abstract
PROCEDIMIENTO DE VALORACION DE MOLIBDENO EN FORMA DE MOO ANHIDRO. COMPRENDE LAS SIGUIENTES FASES: PRIMERA, SE ATACAN EN CALIENTE LOS MATERIALES MOLIBDENIFEROS POR MEDIO DE UN LIQUIDO ACUOSO DE CARBONATO, BICARBONATO O HIDROXIDO ALCALINOS; SEGUNDA, SE REALIZA LA SEPARACION DE UNA FASE LIQUIDA, RESULTANTE DEL ATAQUE, QUE CONTIENE EL MOLIBDENO SOLUBILIZADO; TERCERA, SE SEPARA UNA FASE SOLIDA CONSTITUIDA POR LOS MATERIALES ESTERILES; Y POR ULTIMO, SE ADIFICA LA PARTE LIQUIDA ALCALINA CON UNA CANTIDAD DE ACIDO TAL QUE EL PESO DE ACIDO LIBRE DESPUES DE LA ACIDIFICACION ESTE COMPRENDIDO ENTRE UN 2 Y UN 20% DEL PESO TOTAL DE LA FASE LIQUIDA DESPUES DE LA ACIDIFICACION, Y SE SOMETE A CONTINUACION DICHA FASE LIQUIDA ACIDIFICADA A UNA TEMPERATURA DE 120 GRADOS BAJO PRESION, PARA PROVOCAR LA PRECIPITACION DEL MOO ANHIDRO.
