A review on electrochemical behavior of pyrite in the

The use of electrochemically active grinding media causes galvanic interaction between pyrite and the grinding media during grinding, which results in an effect on the electrochemical behavior of pyrite. In this galvanic interaction, pyrite due to having a higher rest potential acts as a cathode and results in the oxygen reduction on its surface and the production of hydroxide ions.

What You Need To Know About Electrochemical Grinding

A Closer Look at ECG (Electrochemical Grinding) In comparison to electrochemical machining, electrochemical grinding is relatively similar. Basically, it is a combination of an electrochemical process and a grinding process used for metal removal. You may also hear it referred to as "anodic machining" or "electrolytic grinding".
