System and method of processing electric arc furnace dust

摘要

A method of processing electric arc furnace dust includes the steps of preheating a portion of electric arc furnace dust to a temperature of at least 170 degrees centigrade by convection heating to form a preheated dust. The preheated dust is further heated by microwaves until a zinc in the preheat dust vaporizes to form a metal vapor and a residue. The metal vapor is then condensed.
