Core IPEX Improved It’s Ultra-Pure Vanadium Technology

Core IPEX has made excellent progress with refinements to its UltraVan ion exchange technology for recovery of high purity vanadium compounds from waste streams. Improvements include better control over contaminants introduced by reagents and from the entrainment of process liquids during cycle transfers. The effectiveness of these measures was successfully demonstrated in the piloting facilities of IPEX Solutions. The table below shows the high purity composition of V2O5 produced by the UltraVan method.

These results reflect more than a decade of incremental improvements to develop a robust commercial process for producing a range of premium grade vanadium compounds including vanadium electrolyte for vanadium redox flow batteries (VRB). The UltraVan IX flowsheet offers two alterative processes – a vanadyl sulphate APV route and a sodium vanadate AMV route. The following table lists some benefits associated with the two processes.

This new capability is a major achievement for Core IPEX offering strong competitive cost advantages in the emerging high-purity energy metals market. Our SMB IX technology is strongly differentiated from conventional approaches in that high purity compounds may be produced at relatively low cost from a range of resources including calcine tailings, process effluents of primary producers, spent catalysts, fly ash, petroleum coke cinder, carnotite tailings and other waste materials. Core IPEX has entered into discussions with several primary producers to confirm ongoing interest and explore the way forward.
