| Abstract: | The article theoretically and experimentally validates the effective applicability of the electrochemically treated acid wastedump water as a leaching agent for low-grade copper-zinc ores instead of sulphuric acid solutions. The authors have found the way to intensify the Cu-Zn ore leaching by adding 20 mg/l of NaCl in the electrochemically treated wastedump water, which allows the active chlorine concentration of 1.5 g/l and accelerates dissolution of copper and zinc to product solution by a factor of 2.8–6. |
