Alumina

Carnac possesses extensive technical capabilities in engineering services catered to the alumina processing industry from concept to operations support.

Our team is well-versed in Bayer process design and modelling, having gained their expertise in alumina refinery works nationally and globally.

 

  • Undertaking a full refinery flow sheet concept study to assess the opportunities to manage a significant bauxite feed change.

  • Developed a commercialisation flowsheet for a ‘Novel’ process to recovery elements from a bauxite residue area.

  • Developed commissioning strategy and plans for brownfield major decarbonisation upgrade.

  • Feasibility Study for a greenfield alumina refinery, based in south-east Asia.

  • Provided process engineering design for RDA Ferrous Sulphate treatment plant, plus ongoing multi-discipline engineering.

  • Curtailment study for an aging Alumina Refinery.

  • PFS debottlenecking and minor improvements to an existing refinery, for an Australian (south-west) client.
