Abstract

El método de reducir mineral que comprende hacer pasar gas reductor calentado transversalmente por una masa de mineral calentado finamente dividido de pequeña sección transversal con lo cual el gas reductor queda contaminado con agua retirar dicho gas contaminado después de que ha pasado solo una vez a través de dicho mineral sustraer agua del gas calentarlo y hacerlo pasar de nuevo transversalmente a través del mineral.
