Abstract
Article shows the possibility of reduction the impact of galvanic production on the environment due to the processing of spent zinc electrolytes. Analyzed existing methods of treatment of spent zinc electrolytes, allow to reduce the flow of heavy metals into the environment. Presented results confirm the possibility of recycling spent zinc electrolytes to produce pigments. The precipitation of zinc ions from spent zinc electrolytes with sodium phosphate in the presence of admixtures of bright agents and iron compounds, which are most often found in spent electrolytes due to their contamination during operation, was studied.
