Electra has provided construction progress update on its cobalt sulfate refinery, first-of-its-kind in North America. The firm noted that the project continues to advance beyond detailed engineering, with procurement and installation activities advancing. The refinery is expected to become North America’s only battery-grade cobalt sulfate production facility.

Moreover, mechanical completion is targeted for the second quarter of 2027 and commissioning activities soon afterwards. “Steady progress continues at the North American refinery project site,” said Paolo Toscano, Vice President, Projects and Engineering. “With early works now largely complete, including key infrastructure installations and engineering milestones, the project is well positioned to transition into its next phase of construction.”

Engineering work across several process and infrastructure systems is delivering results. The fire suppression system design has been completed. The piping and instrumentation design (P&ID) is also complete. Critical minerals projects are becoming fundamental in North America as the U.S. also advances a $7.4 billion critical minerals plant in Tennessee. 

Scope of Implementation on Electra Cobalt Sulfate Refinery in North America

The completion of the Electra cobalt sulfate refinery seems it will be attained within the expected timeline based on current progress. Electra has completed a comprehensive tailings area testwork program, including test pits, boreholes and also laboratory testing of site samples. Installation of several effluent tanks has now been completed. This expands the site’s process water and effluent management infrastructure.

Moreover, it builds on earlier completed site works including installation of structural pipe racks connecting major process buildings and clarifier tank installations. It also upgrades to site power infrastructure and construction support facilities. Purchase orders for key process systems have been awarded. These include the plant control system, bag breaker system, neutralization clarifier, SX strip solution filter, and PLS filter platform.

Earlier this year, Electra’s Board of Directors approved a US$73 million construction budget and execution schedule designed to advance the refinery. Once operational, the facility will establish a critical piece of North America’s battery materials supply chain by producing battery-grade cobalt sulfate for the region’s growing electric vehicle and energy storage markets.
