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.

Feasibility Study for Significant Reagent Recovery Opportunity

Feasibility Study for Significant Reagent Recovery Opportunity

Carnac identified several high-value opportunities for an alumina refinery that would help the client gain a competitive advantage in the alumina market. One opportunity identified involved recovering reagent from a spent liquor stream. The opportunity was developed by Carnac from a concept to feasibility study level.

Alumina Refinery Upgrade Concept Study

Alumina Refinery Upgrade Concept Study

The client engaged Carnac to undertake a preliminary engineering assessment of required upgrades to achieve an increase in refinery throughput, which included both production generating upgrades, such as those that would increase alumina precipitation yield and liquor flows, and production enabling upgrades.
