Effectiveness acidic pre-cleaning for copper-gold ore

Additionally, the application of a conventional flotation process to extract copper is further complicated when it is oxidized. As a result, an acid pre-leaching process was applied in order to clean the ore of these copper minerals that are cyanide consumers. MUIR, D. M.
