What is the vanadium recovery project?

The Vanadium Recovery Project, a joint venture between Australian companies Critical Metals Ltd and Neometals Ltd, paves the way for a significant increase in high purity vanadium (V) production and self-sufficiency in Europe. The plant is to be situated in Pori, Finland.

Is vanadium a viable resource in Europe?

Although Europe has some vanadium resources, these are mainly deposits of titanium-bearing iron ore containing about 1% of vanadium, or steel slag containing up to 3%. Mining these resources is not economically viable and Europe is therefore highly dependent on vanadium imports, with attendant risks of supply disruptions.

Why is vanadium a promising LDEs solution?

Vanadium contributes to decarbonising hard-to-abate sectors. VRFBs are a promising LDES solution because of their scalability, full depth of discharge, ability to cycle frequently and for long durations, non-flammable construction, and the recyclable nature of the electrolyte. 2.

How can we extract vanadium from V-slag?

The project obtained vanadium extraction rates above 95% in the laboratory. The project partners developed a High Temperature Roasting (HTR) process to extract vanadium from V-slag. This reduces processing time by a factor of ten, and recovers 97% of the vanadium. The project teams also optimised lixiviation and selective precipitation conditions.

What is vanadium used for?

1. Source: Largo Inc, Investor Presentation, May 2022, page 4 Vanadium is a critical raw material used in electric mobility, defence and space and it enables the transition to renewable energy sources via its use in long duration energy storage (LDES) solutions. Vanadium contributes to decarbonising hard-to-abate sectors.

Does slag contain vanadium?

The slag collected from the mills in Raahe, Oxelösund and Luleå naturally contains high contents of vanadium, enabling producing some of the highest purity and cost-efficient vanadium products in the world.
