abstract


The work considers the investigation deposition of zinc ions from the spent zinc electrolyte various Belarusian enterprises to obtain pigments. As precipitants used sodium carbonate, sodium phosphate, sodium hydrophosphate. Studied elemental and phase composition obtained precipitations and the effect of additives, incoming in the spent electrolytes, on composition and properties of precipitations. Selected temperature heat treatment of precipitations depending on the precipitant and obtained zinc oxide, pyro- and ortho- zinc phosphate, which may be used as pigments. Investigate its compliance with GOST on such indicators as the oil absorption and spreading rate.

Obtained results allow to solve the problem of utilization of spent zinc electrolyte solutions, as well as to expand the raw material base for the production of pigments.
