Environmental Constraints Assessment
Alumina

Carnac were engaged to assess the operating limits of an alumina refinery in relation to its environmental licence restrictions.

Carnac’s assessment was successful in providing the client with a go-forward strategy to improve the operation’s return on investment whilst ensuring environmental limits are adhered to.

Prefeasibility Study for an Enhanced Alumina Recovery and Cost Reduction Opportunity
Alumina

Carnac identified several cost reduction opportunities for an alumina refinery via the completion of a Maximum Technical Capability Assessment (debottlenecking study). Carnac further developed the opportunities at a concept level and selected which opportunity to take forward for a prefeasibility study.
