Abstract
The object of research is galvanic production waste in the form of low-concentrated solutions containing nonferrous metal ions. The aim of the work is to develop a hardware and technological complex for deep processing of secondary resources using advanced technologies (membrane, electroflotation, electrochemical). Experimental studies of electroflotation extraction of Ni2+, Zn2+, Cu2+ ions in a flowing electroflotation apparatus with an electro pH corrector were carried out. Optimal conditions of extraction were determined. The mathematical model of the process is created. Two main directions of use of flotation concentrates of individual hydroxides of copper, zinc, nickel, cadmium are proposed.
