Mine Life50 years (as of Jan 1, 2017)
BHP has committed to a series of expansion projects at Olympic Dam in recent years, including a $350 million investment to upgrade the surface operations. The project, the largest planned shutdown undertaken at the asset, ran for over 100 days from August 2017. BHP also used the opportunity to carry out major upgrade works on Olympic Dam’s refinery, concentrator, other key infrastructure and site technology.

Deposit Type

  • IOCG

Summary:

Underground Large poly-metallic deposit of iron oxide-copper-uranium-gold mineralisation.

Mining Methods

  • Sub-level stoping

Summary:

Olympic Dam’s underground mine is made up of more than 450 kilometres of underground roads and tunnels, with a mine depth of 860 metres. The operation extracts copper uranium ore, with the ore hauled by automated train to feed underground crushing, storage and ore hoisting facilities.

Sub-level open stoping underground mine allows selective access to specific grades.

Processing Technologies

  • Hydrometallurgical plant / circuit
  • Flotation
  • Solvent Extraction & Electrowinning

Summary:

Olympic Dam’s processing plant consists of two grinding circuits in which high-quality copper concentrate is extracted from sulphide ore through a flotation extraction process. The operation includes a fully integrated metallurgical complex with a grinding and concentrating circuit, a hydrometallurgical plant incorporating solvent extraction circuits for copper and uranium, a copper smelter, a copper refinery and a recovery circuit for precious metals.
