<p>FIELD: processes and equipment for producing easily volatile metals of their sulfides. SUBSTANCE: aggregate includes two mutually connected furnaces, reduction furnace and converter, all operating at normal pressure that is why material transfer between them is realized at least through one duct at normal pressure. In the result of chemical reactions occurring in furnaces hydrostatic pressure inside furnaces changes, and in addition volumes of melt layers are also changed. Circulation through duct caused by changes provides recycling sulfide matte necessary for procedure out of reduction furnace to converter and recycling melt metal out of converter to reduction furnace. EFFECT: enhanced efficiency of process with use of such furnace aggregate. 9 cl, 2 dwga</p> |
