CHEMICAL GRADE LITHIUM OXIDE BENEFICIATION PLANT

Client: TALISON LITHIUM AUSTRALIA
Project value: $320m
Location: Greenbushes, Western Australia

MSP role: Head contractor EPC contract for the engineering design and construction of a beneficiation plant producing chemical grade lithium oxide concentrate from spodumene-rich pegmatite ores.

Contract type: EPC, incentivised to a Target Cost Estimate (TCE), with agreed Key Performance Indicators (KPIs) for the target cost, and for safety, environmental and IR targets.

Project timing: Construction start 3Q2017, Commissioning start 2Q2019

Several wet separation processes are used to beneficiate the ore

High pressure grinding rollers feed very fine ore into the wet circuit

Talison Lithium Australia’s CGP2 facility is a based around wet processing plant designed to beneficiate spodumene in pegmatite ore sourced from the Greenbushes mining operation.

The facility is the second chemical grade beneficiation plant built by MSP for Talison, and is sized to produce 2.4 million tonnes per annum of chemical grade (~6%) lithium oxide, typically used as a feedstock for chemical lithium production.

MSP’s role included further development of the flowsheet, and appointment as head contractor for the EPC contract work, including a significant presence on site during the construction and commissioning phases. MSP also built a temporary construction camp for the workforce, close to the mine site.

Located adjacent to the mine, the plant comprises primary crushing and high pressure grinding roller circuits, followed by a beneficiation process that includes gravity, heavy media, flotation and high-intensity magnetic separation. The resulting 6% lithium oxide product is dried and bulk bagged for export by road.

Significant packages included: bulk earthworks and civils, structural concrete, structural steel, mechanical equipment and process pipework, tank fabrication and installation, grating and electrical installation.

Specialist packages included: primary crushing circuit and conveyors, heavy pressure grinding roller circuit.

Peak construction workforce exceeded 600, and the project achieved local content of more than 80%.
