Pyrite is reactive and can easily oxidise when exposed to air or oxygen. Pyrite and most sulphide minerals are more inert than the electrochemically reactive grinding media. Therefore, during grinding, grinding media come into frequent contact with sulphide minerals and a galvanic couple is created between the grinding media and sulphides.

General Application. Iron pyrite increases thermal conductivity when used as an active filler in pressed, resin-bonded grinding and cut-off wheels, brake pads, and other friction applications. This increase in thermal conductivity improves the durability of organic bonded abrasives. Balances the hardness/friction coefficient of brake pads.

Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.
