Kinetic evidence is presented showing that the oxidation of sulfide ores is an electrochemical process, similar to the corrosion of metals. The reactions taking place during the aqueous oxidation of zinc sulfide at a temperature below 120 degrees C can be represented by the anodic reaction ZnS Zn (super 2+) +S+2e (super -) , and the cathodic reaction 1/2O 2 +H 2 O+2e (super -) 2OH (super -) .
