Effect of magnetic field on the electroflotation extraction of sparingly water-soluble heavy and non-ferrous metal compounds from wastewater

摘要

Factors that determine the efficiency of extraction of dispersed particles of sparingly water-soluble heavy and non-ferrous metal (Fe, Ni, Co) compounds from wastewater by magnetic treatment followed by electroflotation are discussed. Optimum conditions of the process are found. The results show that exposure of water-dispersed systems to magnetic field can significantly improve the efficiency of the electroflotation extraction of sparingly water-soluble heavy and non-ferrous metal compounds, which can be useful for wastewater treatment industry.
