Abstract

UN PROCEDIMIENTO (10) DE TRATAMIENTO DE UN MATERIAL QUE CONTIENE DIOXIDO DE SILICIO, QUE CONSISTE EN MANTENER UNA ATMOSFERA REDUCTORA CALIENTE EN UNA ZONA DE REACCION (11), Y HACER PASAR UN MATERIAL SOLIDO PARTICULADO QUE CONTIENE DIOXIDO DE SILICIO, A TRAVES DE LA ZONA DE REACCION (11), SIN UTILIZAR SOPORTE. AL TIEMPO QUE EL MATERIAL PASA A TRAVES DE LA ZONA DE REACCION (11), SE PPOSIBILITA QUE EL MATERIAL SE CALIENTE Y REACCIONE, PRODUCIENDO POR TANTO UNA FRACCION RICA EN DIOXIDO DE SILICIO (RAMA 16), Y UNA FRACCION POBRE EN DIOXIDO DE SILICIO (RAMA 18).
