4. Strong applicability: it is suitable for heap leaching, pool leaching and CIP process of oxidized gold and silver ore. The scale can be large or small, and it is more suitable for largescale heap leaching. 5. High leaching rate: it can leach the gold ions effectively and can achieve faster with higher recovery rate than using sodium cyanide. 6.
