The results of research of a new electrocementation method of purification of sulfate solutions in the processing of zinc-containing technogenic wastes of non-ferrous metallurgy and chemical industry enterprises are presented.
On the basis of the results of theoretical and laboratory research and extensive tests, a new technology for recycling zinc-containing man-made waste of non-ferrous metallurgy and chemical industry was developed.
As a result of research it is established that according to ecological, economic and technological factors manufacturing of wall materials for low-rise building by a method of half-dry forming, based on a principle of "zone injection", is the most effective. Laboratory and semi-industrial tests of wall materials obtained from man-made formations according to the proposed technology are close to ceramic and silicate products in their physical and mechanical properties and are not inferior to pressed products manufactured on the equipment of US, Belgian and Italian firms.
