Mineral Sands Plant Debottlenecking / Upgrade

Client/Asset owner: Keysbrook Leucoxene (MZI Resources)
Location: Keysbrook, WA
Duration: Nov 2017 – current

Keysbrook Leucoxene (KLPL) currently operates the Keysbrook Leucoxene mine south of Perth in WA. The operation is a mineral sands mine using dry mining methods and wet gravity concentration of valuable heavy minerals. The plant has been operational for nearly 2 years and KLPL wanted to de-bottleneck and upgrade the plant to achieve a sustained ROM rate of 5.25Mtpa.

The 5.25Mtpa Upgrade Plan consists of a number of sub-projects which collectively will deliver KLPL’s throughput and mineral recovery goals.

The summary level design and project management services include:

  • Design of process plant upgrades and modifications.
  • Design of mine site infrastructure upgrades and modifications.
  • Replacement of the MFU2 lower deck screen panels with larger aperture panels.
  • Reconfiguration of the WCP scavenger spirals to rougher duty with associated pipework changes.
  • Identification of potential options for locating the trommel at the WCP to integrate with existing operations without constraining maintenance and operations activities.
  • Design of new trommel location works, including concrete, steelwork, pipework and electrical to integrate with the WCP.
  • Contractor management and coordination of work with KLPL operations staff during execution of the work.
  • Project management of the relocation and modification works, including attending site while key activities are being carried out, such as shut downs.
