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.

When this cost benefit is added to the lower cost of tailings detoxification, a strong case can frequently be made for cyanide recovery. In most cases, cyanide is recycled by converting it from the free or complexed form in which it exists in gold plants, to hydrocyanic gas, HCN. The negative perception of this highly toxic gas, and concerns ...

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;
