Definition

1. Noun:
   • A mineral (iron and nickel sulphide) that is the chief ore of nickel: Pentlandite is a specific, naturally occurring metallic mineral. It is the primary source from which the element nickel is commercially extracted. Its chemical composition is an iron-nickel sulfide.

Usage Examples

• Noun:
  • The Sudbury Basin in Canada is a major source of pentlandite.
  • Geologists identified the metallic luster as belonging to pentlandite.
  • Nickel is primarily refined from pentlandite.

Advanced Usage

• In economic geology: The term is used to discuss mineral deposits, mining, and resource extraction.
  • The viability of the mine depends on the concentration of pentlandite in the ore body.
• In mineralogy: Used when describing physical properties, crystal structure, or paragenesis (the order of mineral formation).
  • Pentlandite is often found intergrown with pyrrhotite and chalcopyrite.
