Freeport Minerals Corporation (FMC) operates seven open-pit copper mines in North America – Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico.

Deposit Type

  • Porphyry
  • Skarn


Summary:

The Chino mine is a porphyry copper deposit with adjacent copper skarn deposits. There is leachable oxide and secondary sulfide mineralization, and millable primary sulfide mineralization. The predominant oxide copper mineral is chrysocolla. Chalcocite is the most important secondary copper sulfide mineral, and chalcopyrite and molybdenite the dominant primary sulfides.


Mining Methods

  • Truck & Shovel / Loader


Summary:

The available mining fleet consists of thirty-five 240-metric ton haul trucks loaded by four shovels with bucket sizes ranging from 31 to 48 cubic meters, which are capable of moving an average of 235,000 metric tons of material per day.

Processing

  • Flotation
  • ROM/dump leach
  • Solvent Extraction & Electrowinning
