摘　　要：矿浆电解是近年来新兴的一种湿法冶金技术。本文阐述了多金属结核矿浆电解浸出原理,以及浸出电量、酸度、粒度等工艺参数对有价金属浸出率的影响。研究结果表明,采用矿浆电解法在HCl-NaCl体系中处理多金属结核矿是完全可行的,在优化条件下锰、钴、铜、镍有价金属的浸出率均为97%;同时,阳极产出合格的电解二氧化锰。Slurry electrolysis is a new technology of hydrometallurgy developed in recent years.In this paper,the mechanism of leaching ocean polymetallic nodules by slurry electrolysis is expatiated and Effects of technological parameters such as coulomb,pH and particle size on valuable metal leaching are elucidated.The results show that slurry electrolysis is feasible for treatment of ocean polymetallic nodules in the HCl-NaCl medium.Under the optimized conditions,the leaching rates of such valuable metals as manganese,cobalt,nickel and copper are up to 97% without exception and the electrolytic MnO_2 is produced on the anode.
