| Abstract: | The liquid-phase oxidation kinetics of deep-sea manganese nodules in high concentration potassium hydroxide medium is investigated by the effects of factors on the conversion rate of manganese in the deep-sea manganese nodules such as reaction time, reaction temperature as well as oxygen partial pressure. The experimental results indicate that liquid-phase oxidation reaction of manganese nodules can be described by non-reaction core shrinking model. The oxidation reaction process with apparent activation energy of 53.26kJ/mol, is under control of interface chemical reaction. |
