Pyrite | Common Minerals
Fire was pyrite's most prominent gift to human society. Sparks are created when pyrite is struck against metal or a hard surface and this was one of the earliest methods humans discovered to create flame. Pyrite's name comes from the Greek phrase, 'pyrite lithos,' which means 'stone which strikes fire.'. Its brilliant metallic ...

Mineral Processing | SpringerLink
Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals. In the early years, mineral processing was called mineral concentration or mineral engineering in China.
