Abstract
The object of the research is electroplating production wastes in the form of low-concentrated solutions containing non-ferrous metal ions (primarily Ni2+, Zn2+, Cu2+). The aim of the work is to develop apparatus and technological complex for deep processing of secondary resources using advanced technologies such as membrane, electroflotation, electrochemical. In the process of work experimental researches of electroflotation extraction of ions Ni2+, Zn2+, Cu2+ in the flowing electroflotation apparatus with the electrical pH corrector were carried out. The optimum conditions of extraction are determined. The mathematical model of process is created. Two main directions of using flotation concentrates of individual hydroxides of copper, zinc, nickel and cadmium are proposed.
