Abstract:

Heap leaching of oxidized, complex, and waste copper ores of the Volkovskoe deposit is considered. Based on the results of an investigation, the preliminary granulation of milled ore with sulfuric acid (25-75 kg/t ore) is recommended. Introduction of this procedure leads to a decrease in the leaching time by 15-30\% and allows one to obtain solutions more concentrated by copper. For 90-100 days, the recovery of copper into the solution amounted to 65-72\% for the waste ore, 76-78\% for the oxidized ore, and 46-50\% for the complex ore. An increase in leaching time leads to an increase in the recovery of copper from all types of ores.
