Abstract
Oxides on the surfaces of metal are reduced by directing reducing gases at them in a forceful and turbulent manner. In a preferred version, the gas is passed through at least two reducing zones designed to maintain a higher concentration of reducing gas in at least one of them than would be the case in a single reducing zone. The oxide-bearing surface is heated at the beginning of the process.
