Abstract:
The results of the development and the implementation of new technologies of metallurgical wastes, containing such non-ferrous metals as zinc, lead, tin are presented in the work. Electric furnace steelmaking dust, copper plant dust and dross were recycled with the recovery of valuable components.
As a result of recycling, the following marketable products were produced: zinc as metal, lead and tin as concentrates and iron as iron-containing clinker. Implementation of new technologies allowed JSC "Chelyabinsk Zinc Plant" (JSC "CZP") to produce more than 10 thousand tons of zinc as metal and 4 thousand tons of lead and tin in concentrates annually due to metallurgical wastes recycling.
The main research and technology idea of the metallurgical wastes recycling technology usage is distilling separation of the elements of complex-component oxide systems in reductive conditions in the rotary tube furnaces.
On the base of completed studies, the new process flowsheet and new technical solutions were produced. These solutions are implemented in all stages of production: raw material preparation for metallurgical processing; volatilization of zinc, lead and tin in the tube furnace (I stage of Waelz-process); pyro-selection of lead (II-stage of Waelz-process); fumes preparation for hydrometallurgical recovery of zinc in the solution, directed to electrolysis with the producing of branded metal, lead and tin in concentrates.
