Factors and treatment methods of nickel ion depletion when nickel is deposited by electrolytic diaphragm

When electrolytic diaphragm cloth is electrolytically depositing nickel, various situations will occur due to factors such as liquid level difference, ph value, current flow, etc., which will not only interfere with filtration efficiency, but also may cause property damage. When electrowinning nickel, nickel ion depletion will occur So, what are the factors and treatment methods for the depletion of nickel ions when the electrolytic diaphragm is used for nickel deposition?

First, the factors of nickel ion depletion

The cathode and anode electric efficiency is poor. During the whole process of electrolysis, the cathode electric efficiency is usually 96%, while the anode electric efficiency is higher than 85%. During the process, various slags take away a large amount of nickel, which interferes with the depletion of nickel ions.

2, method

1. The whole process of electrolysis is carried out as planned, wipe the contact points, scrape the anode mud, ensure the anode conducts and dissolve well, and improve the anode efficiency.

2. Strengthen the cleaning operation of various slag and reduce the nickel content in the slag.

3. Improve the current intensity in the whole process of liquid making, and improve the ability of making liquid to replenish nickel.
