Whilst cyanide is one of the major drivers if not the major driver of gold dissolution, it cannot be viewed in isolation particularly in respect to the relationship between cyanide and oxygen derived from Elsner's equation: [1] From the Equation, it is apparent that both cyanide and oxygen are required in an aqueous solution in order to leach gold.

For example, copper–gold ores consume cyanide whilst carbonaceous (pregrobbing) material in gold ores adsorb gold cyanide and prevent the solubilization of gold. The silica encapsulation and the association of gold with sulfide minerals make the refractory gold ores resistant to gold cyanidation, even after fine grinding.
