This is actually lower than the gold extraction with cyanide-free glycine leaching (90%). These findings, together with the low price, high re-cyclability and non-toxicity of glycine, suggest that glycine leaching can be considered as a viable cyanide-free method for recovery of gold from mildly refractory gold ores.

· Pyrite is found in many kinds of gold ores, such as sulfur, tellurium, and carbonaceous gold ores, and it is closely related to gold (Qin et al., 2021). In carbonaceous gold ores, the close relationship between pyrite and gold is often in the form of gold-locking by pyrite ( Fleet and Mumin, 1997 , Kovalev et al., 2011 ).
