GPS Joins FEED and Optimisation Team for Colluli Project

Global Potash Solutions (GPS) joins front end engineering design (FEED) and optimisation team for Colluli potash project in Eritrea

GPS was the one that oversaw the metallurgical test program, process flowsheet development and initial optimisation work for the Colluli potash project throughout the pre-feasibility and definitive feasibility study phases of the project.

Danakali Limited (ASX:DNK) is pleased to advise that Global Potash Solutions (“GPS”) has been appointed to join the front end engineering design (FEED) and optimisation team for the Colluli Potash Project.

GPS has extensive technical and operational experience in the global potash industry, supporting projects in the United States, Canada, South America, Middle East, North Africa and Australia. GPS has provided expertise and technical support to Arab Potash Corporation, Potash Corp., BHP Billiton, and Karnalyte Resources, as well as completing third party due diligence on potash projects for a number of engineering firms.



GPS provides services in potash process plant design, independent technical due diligence, hazard and operability studies, piping and instrumentation diagram reviews, auditing of construction, and commissioning and start-up.

GPS oversaw the metallurgical test program, process flowsheet development and initial optimisation work for the Colluli potash project throughout the prefeasibility and definitive feasibility study phases of the project.

The initial process optimisation work resulted in a reduction in process water requirements of over 70% between the PFS and DFS phases. GPS will work closely with the Fluor process engineering team on process optimisation, equipment selection and commissioning procedures.

Danakali Managing Director, Paul Donaldson said “We are delighted to continue our working relationship with Global Potash Solutions, and look forward to their continued contribution to the technical and operational elements of the project. Their extensive technical knowledge and operational experience has been of immense value to the project to date, and we look forward building on this as we advance to construction.”

Global Potash Solutions CEO, Don Larmour said

“We have worked on numerous projects throughout the world and bring considerable expertise in potash processing design, operations management, commissioning and maintenance. Our involvement in the project throughout the prefeasibility and definitive feasibility study phases, has given us an excellent understanding of the Colluli project, and we believe we can make a considerable contribution to the optimisation of the process design. We are very pleased to be able to continue our long-term contribution to the Colluli Potash Project, as we believe this project has very high potential, given its simplicity, ideal combination of potassium salts and the capability of the teams we have worked with throughout the study phases on this project. Colluli is the most advanced greenfield potassium sulphate development we’ve had the pleasure to be involved with and the Colluli Potash Project has excellent potential for development and long term sustainability.”

Colluli is one of the most advanced greenfield sulphate of potash (SOP) developments in the world, and demonstrates outstanding economics including industry leading capital intensity, bottom quartile operating costs, close proximity to coast and key markets and unrivalled product diversification potential.

Approval of the social and environmental impact assessment (SEIA) for the project was given by the Ministry of Land, Water and Environment in December 2016. The award of the Mining Agreement and Mining License for the project is well progressed.
