Carnac identified a high-value Greenhouse Gas (GHG) reduction opportunity for an alumina refinery. Carnac were subsequently engaged to complete a Pre-Concept Study for technical validation of the opportunity.
Environmental Constraints Assessment
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
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.
Tailings Liquor Treatment Plant Debottlenecking Study
Tailings Liquor Treatment Reagent Logistics and Supply Study
Future Bauxite Ore Impacts Concept Study
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.
