During hydrometallurgical Nickel/Cobalt production process reactions decrease pH continuously, to regulate pH calcined magnesia can be used as a regulator.
Advantageous of calcined MgO over NaOH as pH regulator;
1- Remove sodium content
2- Prevent sudden pH increment
3- Cost stability
4- Environmental friendly
