Greenbushes Lithium Crushing Plant


Talison Lithium


Greenbushes, Western Australia




CPC has recently completed the engineering design for a 500 t/h Chemical Grade Plant 2 (CGP2) crushing circuit at Talison Lithium’s Greenbushes Plant in Western Austalia. The circuit includes primary and secondary crushing (jaw, cone), HPGR, screening, interconnecting conveyors and a stockpile reclaim.

The CGP2 expansion will effectively double the lithium concentrate production of the current Greenbushes lithium processing facility, with the crushing plant processing 2.4 Mtpa of spodumene ore. CGP2 was commissioned late 2019.

Immediately following the completion of CGP2 crushing circuit, CPC commenced the design for the 1,000 t/h Chemical Grade Plant 3 (CGP3) project. This expansion project will provide an additional 4.8 Mtpa of spodumene ore processing capacity for Talison Lithium. Detail design has concluded.


  • Special design of CGP2 and CGP3 to handle highly abrasive nature of lithium – hardier than standard plants
  • Sizeable plant design to allow for high through put from large operation
  • CGP2 and CGP3 to provide more raw material to expanded back end of Talison’s Greenbushes facilities

Highlights and Achievements

  • Unique approach due to client requirements of tight delivery deadline with concrete poured prior to structural design completion
  • Availability of multidisciplinary workforce enabled delivery in short timeline

Benefits for Client

  • Could incorporate learnings on critical issues from CGP2 into CGP3 due to time overlap in construction
  • Higher throughput capability – CGP2 more than doubled production at the mine
