Tivan achieves high-purity vanadium specification at Speewah

  • Tivan has completed a salt roast testwork program for the Speewah Vanadium Project that successfully produced high-purity vanadium pentoxide (V2O5) with a grade of 99.86% V2O5 without the use of solvent extraction.

  • The testwork program was announced in February 2024 and was designed to evaluate the commercial viability of development pathway from Speewah ore to vanadium flow batteries (“VFB”).

  • The V2O5 produced is being used for vanadium electrolyte (“VE”) preparation and testing at the University of New South Wales specifically targeting achievement of the VE specifications of Sumitomo Electric Industries. These results are expected in Q1.

  • Tivan continues to progress its assessment of two vanadium processing technology pathways: TIVAN+ in strategic partnership with CSIRO and a conventional salt roast processing flowsheet.

The Board of Tivan Limited (ASX: TVN) (“Tivan” or the “Company”) is pleased to provide an update on the vanadium electrolyte testwork program being undertaken for the Speewah Vanadium Project (“Speewah”) in Western Australia. This forms part of an assessment of two separate vanadium processing technology pathways under consideration for Speewah: the TIVAN+ processing technology in strategic partnership with CSIRO and a conventional salt roast processing flowsheet (see ASX announcement of 27 September 2024).

As previously announced, excellent preliminary testwork results had been achieved for both the TIVAN+ and salt roast technology pathways, providing Tivan with significant development optionality (see ASX announcements of 30 May 2024, 19 June 2024; 27 September 2024).

For the conventional salt roast pathway, Tivan has completed a testwork program that included desilication trials, purification trials and a set of bulk trials for the flowsheet from concentrate through to vanadium pentoxide production.

The testwork program was highly successful, producing high-purity V2O5 with a grade of 99.86% V2O5 without the use of solvent extraction. The V2O5 is suitable for the next phase of testwork targeting production of high-purity VE at the specifications provided by Sumitomo Electric Industries (“SEI”), a Japanese manufacturer of large-scale, long-life vanadium flow batteries (see ASX announcement of 28 February 2024).

Vanadium Electrolyte Program Development

The VE development program comprised of a set of sighter tests designed to assess the amenability of preparing a VE sample that meets the SEI specification, using the traditional salt roast method for vanadium extraction from Speewah vanadium titanomagnetite (“VTM”) ore.

The technical highlights from the program are as follows:

==> picture [596 x 127] intentionally omitted <==

Desilication

Desilication trials were designed to investigate a broad range of conditions across a number of tests with a focus on the impact of reagent dosing, pH and temperature. The outcomes from the desilication work were positive, demonstrating that there are parameters that will be suitable to prepare either a standard (98.5% V2O5) vanadium pentoxide product or a high purity >99.5% V2O5 product.

  • 99% Si removal and <2% vanadium loss to prepare a solution better suited to preparation of a standard grade V2O5

  • 99% Si removal and ~5-10% vanadium loss to prepare a solution better suited to preparation of a high-purity V2O5 product

Purification

The purification trials were preliminary tests to investigate two methods for upgrading the vanadium bearing solution prior to ammonium metavanadate (“AMV”) calcination. AMV calcination is the standard industry process for preparing vanadium pentoxide. Solvent extraction shake tests were performed for three solvents for a range of processing parameters. The solvent extraction trials identified a promising solvent that could be utilised for future flowsheet development. Due to additional costs, solvent extraction is not Tivan’s preferred method for purification of the vanadium solution and the need for development will be assessed before commissioning any future work programs.

The alternative tested purification flowsheet is simpler than a solvent extraction flowsheet, utilising precipitation reactions to purify and separate out a higher quality AMV product. These tests were very successful, preparing high purity AMV products at ~4% vanadium loss. This was selected as the preferred method for the bulk V2O5 preparation trials (see below).

Bulk Trial

~35 kg of Speewah VTM concentrate (2.44% V2O5) was processed from salt roasting through to AMV calcination, to prepare a V2O5 sample for VE testing. The testwork program was executed at ALS Balcatta utilising bulk batch conditions for each unit process.

The final vanadium pentoxide product has met the high purity target, achieving a grade of 99.86% V2O5.The high purity product is considered suitable for VE testing.

Summary

A goal of the program was to produce the high-purity V2O5 sample without the use of solvent extraction to simplify the flowsheet and reduce potential project costs. The alternative purification process trialled in this program met this goal and is a suitable processing solution as demonstrated by the outstanding vanadium pentoxide product grade.

The bulk testwork conditions for the desilication and purification areas were based on preliminary un-optimised batch conditions. Future testwork will include optimisation of processing parameters to target increased overall vanadium yield. Furthermore, in engineering studies, the viability of industry standard salt roasting flowsheet recycle streams will be investigated to improve the total plant recovery.

Refer to Appendix 1 for desilication and purification results.

Next Steps

The program has successfully achieved the target high-purity vanadium pentoxide specification, and the sample is now being used for VE preparation and testing. This program has commenced at UNSW and is expected to be completed in Q1. Tivan will provide an update on the final outcomes of the program following completion.

As previously announced, since the publication of the CSIRO TIVAN+ testwork results in May 2024, Tivan has received significant third-party interest in the technology, including from VTM resource owners in Australia and overseas (see ASX announcement of 27 September 2024). Tivan continues to advance opportunities for collaboration in conjunction with CSIRO and expects to provide a status update in Q1. Tivan notes that while there is significant third-party interest in the TIVAN+ technology, there is no guarantee or certainty that a commercial arrangement or sublicensing agreement will eventuate.

Tivan Executive Chairman Mr Grant Wilson commented:

“The outstanding testwork results achieved by Tivan’s process engineering team confirm Speewah’s status as Australia’s premier VTM resource and the technical viability of the pathway to supply vanadium flow batteries at scale. Speewah’s comparative advantages include high vanadium in concentrate grade, low strip ratio, close proximity to port and vast size. In addition, the Speewah Fluorite Project will introduce enabling infrastructure to the site location, further reducing project costs and establishing a durable social licence to operate in the East Kimberley region.

While the commercial pathway to develop a vanadium project in Australia remains challenging, the testwork results and our rapid progress with the Speewah Fluorite Project, put Tivan in poll position. We will continue to advance the project development pathway, ensuring that the Speewah Vanadium Project contributes to Tivan’s sum of parts valuation and in support of the development of long-duration energy storage capabilities across northern Australia.”

This announcement has been approved by the Board of the Company.
