gold cyanidation chemistry

An improved rate equation for cyanidation of a gold

Although cyanide and oxygen are the key reagents in conventional gold cyanidation, previousic investigations of gold dissolution from ores have grouped together the free cyanide and dissolved oxygen concentrations into the rate constant of each equation that was proposed.
