Maboumine Demonstration Plant

Challenges

ERAMET is developing a new process to recover niobium, rare earth elements, and uranium from a deposit in Gabon owned by Maboumine.
A prefeasibility study and a feasibility study were needed for a 1:200-scale demonstration pilot plant that will prove the chemistry and optimize the flow sheet before the commercial plant is constructed.

Solutions

Process modifications that dramatically improved the operating efficiency of the process were identified.
The demonstration plant was designed to test the performance of the novel flow sheet on a small scale. Design criteria will be optimized and extracted prior to launching the large commercial plant project.
Our experts helped plan and oversee test work to design the demonstration plant, facilitate technology selection, and determine appropriate materials for the plant's construction.

Highlights

The technical improvements that were suggested bolstered the project's economics, particularly around the leach circuits.
The use of a modularized design for most of the demonstration plant was a key feature, motivated by the remoteness of the site and the size of the facility. Ultimately, it increased confidence in the schedule and the quality of the work during execution.
Comprehensive infrastructure that supported the site was designed, including water supply, power generation, and a site camp.

“Thanks again for your contribution to our project ... I hope we will be able to work together again in the future.”
