KEY POINTS
- Electra says construction of its Ontario cobalt refinery is advancing rapidly.
- Major contractors are working on processing circuits, equipment, steel, concrete and piping.
- Selected commissioning is targeted for Q4 2026, with commercial production expected in Q4 2027
Electra Battery Materials Corporation says construction of its cobalt sulphate refinery in Temiskaming Shores, Ontario, is gathering pace, with several major work packages now being executed as the company moves closer to commissioning the strategic critical-minerals facility.
The project is being developed as a key North American source of battery-grade cobalt sulphate, a material used in lithium-ion batteries and energy-storage systems, as well as defence and other industrial applications.
Electra said significant progress has been recorded at the refinery since its previous construction update in June.
Current activities include structural steel and concrete works, installation of processing equipment, preparation for piping works and the selective removal of old infrastructure at the brownfield site.
The company said the refinery is now visibly taking shape as contractors advance work across several sections of the facility.
Engineering for the project is also substantially complete, allowing construction teams to focus on delivering the remaining infrastructure and equipment within the planned schedule.
Contractors Push Ahead With Key Processing Circuits
Several contractors have been appointed to undertake important parts of the refinery’s construction.
WB Melback Corporation is carrying out work valued at about C$26-million, while Pro Pipe Construction has secured a C$6.8-million contract. Their work includes activities linked to the solvent extraction and crystalliser circuits, which are central to the refinery’s processing operations.
Meanwhile, Electra is finalising another mechanical and piping construction package with Kilmarnock Enterprises.
Kilmarnock has already mobilised at the site and established an onsite fabrication facility. The facility is expected to support construction and equipment installation at the existing refinery.
Its wider responsibilities cover civil and concrete works, structural steel installation, process equipment installation, as well as the fabrication and installation of piping.
The refinery is a fully permitted brownfield project and is being developed with support from the US, Canadian and Ontario governments.
The facility is considered strategically important because North America is seeking to strengthen domestic and regional supply chains for critical minerals and reduce reliance on external sources for materials needed in advanced manufacturing and energy technologies.
Cobalt remains an important component in several lithium-ion battery technologies, particularly those used in electric vehicles and energy-storage systems.
