  • Pyrite Mineral Uses and Properties

    Other usesCharacteristicsPropertiesAppearanceCompositionIndustryUsesEffectsSafetyFormationThe name \"pyrite\" is after the Greek \"pyr\" meaning \"fire.\" This name was given because pyrite can be used to create the sparks needed for starting a fire if it is struck against metal or another hard material. Pieces of pyrite have also been used as a spark-producing material in flintlock firearms.
