Leading vertically integrated and conflict-free provider of high performance tantalum metallurgical and powder products to the electronics, aerospace, automotive, chemical manufacturing and other industries.


The primary source of tantalum is from minerals such as tantalite, columbite, wodginite and microlite contained in pegmatite ore bodies. The largest deposits are located in Australia, Brazil and Africa. However, the tantalum market is supplied from a variety of sources:

  • Primary production of tantalum-bearing minerals by conventional mining operations
  • Artisanal production of tantalum-bearing minerals
  • Synthetic concentrates produced from tin slags and accumulated tin-mining wastes
  • Material from inventories within the supply chain
  • Intermediate materials such as tantalum oxide, K-salt and metal
  • Recycled consumer and processor scrap and other secondary materials
