Grinding Media — Its Effect on Pulp Chemistry and

A considerable volume of work exists in the literature examining the electrochemical interactions between grinding media and sulfide minerals. Broadly, most sulfide minerals are more noble than forged steel grinding media used during comminution, therefore a galvanic couple between the media and the sulfide mineral(s) exists, which increases the corrosion rate of the grinding media.

Corrosion of grinding media can affect its longevity (internal structure) and performance. This is generally the case in mills where chemicals, water with an acidic pH level or the ore’s characteristics create a corrosive environment. A way to combat this is higher chromium content in the grinding media. Grinding media with higher chromium
