ASX-listed Danakali has completed the final appointments to the Colluli front end engineering design (FEED) team and has started the optimisation process.

The final two appointments to the FEED team include consulting firms Knight Piésold and Elemental Engineering.

Knight Piesold provides services to the mining, power, water resources, infrastructure and oil and gas industries and specialises in creating tailored solutions at every stage of a project life cycle.

Knight Piesold has led numerous award-winning projects to completion and has an intimate understanding of the Colluli project, as a result of the significant contribution they made to both the prefeasibility and definitive feasibility studies -in the areas of surface water modelling, hydrogeology, potassium recovery pond design and site geotechnical investigations.

Meanwhile, Elemental Engineering provides world leading process simulation and process development services to the minerals processing industry and completed the mass balance modelling work for both the prefeasibility and definitive feasibility studies for the Colluli potash project.

The FEED process is led by engineering and construction firm Fluor, who was appointed in early January.

The process has commenced with the FEED team assembling for the first phase of value engineering and optimisation.

Danakali has a completed a definitive feasibility study, which demonstrates a world-class project with a massive 1.1 Bt ore reserve, industry leading capital intensity, bottom quartile operating costs and unrivalled product diversification potential.

Danakali continues to work to secure a mining agreement and mining license and believes that it can conclude this step of the process shortly.
