Abstract
A process of purifying complex multicomponent technological solutions with the use of a combined sorption-and-electrochemical method was studied. By the example of processing the technological solutions from the Belovo Zinc Plant and from the sulphuric acid workshop of the Ural Mining and Processing Company, a potentiality of combined using the adsorption and electrochemical stages for efficient extracting of HMI and arsenic up to attaining required MPC standards for discharging the solutions into a sewage system was demonstrated. This allows reducing to a significant extent the hazard inherent in the wastewaters and technological solutions, improving the environmental situation around the enterprises and reducing the metal loss.
