Some applications of galvanic manufacture waste

Abstract

In the work various directions of use of galvanic manufacture waste have been investigated. As a result of their analysis and experimental data the conclusion is drawn on impossible application of sewage deposits of galvanic manufacture as the additive for concrete mixes making due to their ecological danger. However, the given sewage deposits can be used in manufacture of a ceramic brick and colour glaze under condition of the obligatory ecological control of finished products. It is preferable to apply these deposits for colour glazed coverings as it is possible to substitute pigments by manufacture waste. It is also perspective to extract metals from sewage deposits of galvanic manufacture. Realization of the named directions will allow us to turn the given waste into valuable secondary raw materials, to expand an industry raw-material base, to lower negative influence on environment.
