Possibilities of zinc extraction from galvanic sludges by means of electrolysis
The aim of the work is a proposal of innovative technology of metal waste processing – sludges and filtration cakes from galvanizing plants. The paper deals with possibilities of zinc obtaining from waste of galvanic sludge, which arises during galvanic plating. A leaching process in an acid environment was optimized in the laboratory, resulting in separation of iron and organic components from sludge. The obtained leach was processed by means of the electrolysis in order to get pure zinc. Results of chemical analyses of individual products at the hydrometallurgical processes are presented in the article.
