Laboratory electrolytic manganese
Thread Content
I am new to electrolytic manganese; I tried to produce it in the laboratory today, but it wasn’t successful. The mother liquor was not thoroughly purified; Ni and Co levels were too high, preventing electrowinning, and the cathode plates turned black ； There was also a power outage once during the electrolysis process. I would like to seek guidance from those in the industry. I greatly appreciate the sharing of knowledge and experience.
I haven’t been here for a long time~~~~~~~~ What’s the question, OP?
