摘要: Abstract The concept of mixed potentials has been applied to explain important aspects corrosion for many years. In hydrometallurgical systems, reactions occur by means electrochemical mechanisms. Application potential theory the kinetics oxidative and reductive leaching processes is a useful in explaining observed results qualitatively. It explains often rapid shift from one kinetic regime another provides basic information regarding sequential phase changes. Quantitative application requires knowledge individual electrode kinetics. From kinetics, overall reaction may be calculated. Examples are presented contact reduction, cyanidation sulfide leaching.
