通过研究温度对多金属结核中锰还原反应的影响，考察了大洋多金属结核亚铜离子催化还原氨浸的动力学．试验结果表明，要获得较高的镍、钴、铜浸出率必须尽可能实现结核中锰的还原．结核中锰还原反应用未反应收缩核模型描述，反应受表面化学反应控制． By studying the effect of temperature on the reduction of manganese in polymetallic nodules, the kinetics of catalytic reduction of ammonia by polymetallic nodules with cuprous ions was investigated. The test results show that, in order to obtain high leaching rate of nickel, cobalt and copper, the reduction of manganese in the nodules must be achieved as much as possible. The manganese reduction reaction in tuberculosis is described by an unreacted contractive nuclear model, and the reaction is controlled by the surface chemical reaction.
