Intensive Cyanidation
Intensive Cyanidation Reactors (ICR) are used primarily for the gold leaching of high grade concentrates such as gravity concentrates. While applications exist for low volume high grade refractory gold ores, operational costs make intensive cyanidation reactors most viable on higher grade concentrates.
