In the article the results of processing oxidized copper polymetal ore and iron ore tailings by heap leaching irrigation and sorption methods have been analyzed. A study was made of conditions for concentrating some non-ferrous metals (Cu, Zn, Ag, Au, Co, Mn) by hydrolytic precipitation and sorption methods. As well, it is reported on the results, were obtained, on utilization of arsenic from technological solutions to the demand level of concentration.
