摘要:
Method for the pyrometallurgical treatment of iron oxides and/or zinc oxides and/or heavy metals, such as those contained in the fumes of electric arc furnaces, whereby the oxides and possibly the heavy metals are fed into a rotary furnace (21) so as to obtain oxides of heavy metals and/or cast-iron, the oxides being collected (34) and sent to a distillation furnace (67), whence the heavy metals are obtained in the liquid state.
