The present invention discloses a system and method for using a pressurized oxy-fired configuration to conduct metal reduction. The invention discloses a process for production of metal from metal oxide ore through reduction, comprising: (a) feeding a mixture of metal oxide ore, fuel and supply of oxygen into the inlet of a metallization reactor, (b) heating the mixture of metal oxide ore, oxygen and fuel in a primary reduction zone of the metallization reactor at a pressure exceeding ambient pressure to produce a product mixture; and (c) separating the product mixture in a gas separation unit at the bottom or downstream of the metallization reactor.
