摘要

The article presents the results of a study on the flotation enrichment of oxidized copper ores from the Zhezkazgan deposit using electrochemical pulp preparation. It is shown that preliminary electrochemical treatment promotes the activation of the mineral surface and increases their flotation. The optimal pulp processing parameters were determined using the mathematical design of experiments. The application of this technology allowed for an increase in copper recovery in concentrate from 75.2 to 85.6% and an increase in the copper content in concentrate from 8.42% to 10.35%. The obtained results confirm the potential of using electrochemical activation for refractory oxidized copper ores [1, 7, 9].
