Manhes process \Man`h[`e]s" proc"ess\ (Copper Metal.)
A process by which copper matte is treated by passing through
it a blast of air, to oxidize and remove sulphur. It is
analogous in apparatus to the Bessemer process for
decarbonizing cast iron. So called from Pierre Manh[`e]s, a
French metallurgist, who invented it.
