Effectiveness acidic pre-cleaning for copper-gold ore

Cyanidation is the most common method employed to recover gold and silver from their respective ores. In this process, other metals, besides gold and silver, can be dissolved in certain circumstances and interfere with the extraction efficiency of these targets. Copper is one of these metals, being able to reach concentrations as high as 1,000mg/L.
