ABSTRACT:
A method for reducing the metal oxide content of a particulate ore to the metallic state, the ore having a particle size such that at least about 85% thereof will pass through a 200 mesh screen. The particles are entrained within a turbulent stream of reducing gas for the metal oxide for a time and at a temperature sufficient for the reducing gas to react with and reduce the ore to a finely divided metal to at least partially oxidize the reducing gas. The turbulence imparts to the particles sufficient kinetic energy to prevent agglomeration thereof.
