ABSTRACT:
A process for the reduction of zinc roast in which pulverized particles of zinc roast are fed into an arc heated jet of carbon monoxide, whereby the particles are heated and reduced from zinc oxide to zinc vapor which in turn is quenched with pulverized carbon in an endothermic reaction to yield additional carbon monoxide, after which the vaporized zinc is cooled to room temperature.
