ABSTRACT:
A process for producing metals in the reduced state from their oxides using a simple and less expensive facility with lower running cost. A metal oxide in the form of particles is supplied into a high temperature flame from an oxygen burner in a reactor furnace to heat and melt the metal oxide. A reducing agent is also supplied into the flame to cause a reducing reaction of the molten metal oxide with the reducing agent. The resulting metal is recovered.
