Neometals Ltd. announced successful completion of the continuous pilot trial ("Pilot") for the Company's Vanadium Recovery Project ("VRP"). The trials processed approximately 14 tonnes of vanadium-bearing steel by-product ("Slag") over 24 days from 3 Scandinavian steel mills. Results confirmed excellent vanadium chemical product purity (consistently higher that 99.5% V2O5) and strong recoveries (recoveries exceeded 75% during steady state) for Neometals' patent pending hydrometallurgical process for recovering vanadium from Slag. As previously announced, Neometals executed a collaboration agreement with Critical Metals Ltd. ("Critical"), to jointly evaluate the feasibility of constructing a facility to recover and process high-grade vanadium products from Slag generated by steel producer SSAB in Scandinavia. Neometals is funding and managing the evaluation activities, including pilot trials and evaluation studies up to consideration of a final investment decision, which, if positive, will earn Neometals a 50% interest in an incorporated joint venture ("JV") with Critical. Neometals reported the Pilot was constructed, commissioned and operated continuously through three trials without any safety incidents or process challenges. The Pilot confirmed, at a 25 times higher throughput rate, the earlier mini-pilot plant results. Of particular importance was the increase in vanadium concentrations achieved during the Pilot which offers potentially significant operating and capital cost savings in the product recovery stages of the process. Passing this major technical milestone is important and gives Neometals strong confidence to select engineers, commence the Feasibility Study ("FS") and provide larger samples for product evaluation and offtake discussions. The Neometals vanadium processing flowsheet involves comminution followed by leaching in alkaline carbonate process water, an integrated three stage leach with interstage regrind circuit and finally leach discharge filtration and solids washing. The solid residue is repulped and washed to further recover soluble vanadium (and sodium) species and lower the levels of these elements in the final leach residue, a stabilised slag material ("SSM"). The `pregnant leach solution' ("PLS") is further filtered to remove any colloidal silica prior to the vanadium selective solvent extraction circuit which produces an alkaline vanadium strip solution appropriate for a conventional vanadium pentoxide ("V2O5") circuit involving desilication, ammonium metavanadate ("AMV") precipitation and subsequent calcination (de-ammoniation). The Pilot was undertaken at a commercial laboratory in Perth, Western Australia and represents part of the pre-development activities for a proposed vanadium recovery JV targeting production of high-purity vanadium pentoxide, V2O5. Neometals milled and processed over 14 tonnes of Slag in three campaigns, sequentially processing Slag from SSAB's Luleå, Raahe and Oxelösund operations. Targeting 25 kg/h dry Slag equivalent feed to the leach circuit, the Pilot operated for 576 incident free hours over the three campaigns including milling, leaching, solid liquid separation, repulp washing of leach residue, PLS conditioning, solvent extraction, desilication and AMV production. During the campaigns, approximately 40m3 of PLS was generated and processed through a conventional mixer-settler solvent extraction system incorporating extraction, scrub and strip stages. At steady state higher than anticipated strip liquor concentrations of vanadium were consistently generated and these were processed through conventional desilication, AMV precipitation. Subsequent AMV de-ammoniation produced V2O5 with a purity consistently exceeding 99.5%. The improvement in strip solution concentrations reduces the processing volumes, the consumption of sodium hydroxide and sulphuric acid and the volume of sodium sulphate by-product that will be generated in the flowsheet. All of these factors have a positive implication in reducing the potential size of the purification and product handling circuit and associated operating and capital costs. AMV and V2O5 product samples are already en-route to potential off-take partners in Europe and Japan for testing in high tech applications (including testing in batteries) The residual material from the leach circuit was removed using a pressure filter and washed on the filter to reduce potential entrainment losses of vanadium or reagents to the solids. The solid residue from the process was repulped in warm water to further remove soluble vanadium and sodium containing species and return the target value metal and reagent to the leach circuit. The vanadium in wash waters is collected by ion exchange and concentrated in the eluant before being returned to the vanadium purification circuit. The well washed leach residue, SSM, is expected to be a by-product potentially suitable for use in a range of industries such as concrete and building materials. Following Neometals' initial market evaluation studies, samples of this SSM, generated from the Pilot have been dispatched to a number of potential users in Europe. In a commercial operation, the Neometals/Critical JV anticipates feeding 200,000 dry tonnes per annum of Slag into a circuit which will incorporate a multi-staged integrated mill/leach circuit using a weakly alkaline sodium carbonate leaching system at atmospheric pressure and only moderate temperatures. The carbonate in the leach circuit is regenerated using up to 65,000 tonnes per annum carbon dioxide (the most voluminous reagent in the flowsheet) while top-up sodium carbonate will be used to replace any sodium ions lost in the solid residue. The carbon dioxide will be sourced from an emission source and thus the operation is expected to be extremely low or at `net zero' in terms of carbon footprint /carbon dioxide emissions. The Pilot has confirmed an optimal process flowsheet and reagent regime. Neometals is now finalising the process design package and engineering contractor selection to deliver an AACE Class 3 (Feasibility) Study to SSAB by 30 June 2022. The product samples (AMV, V2O5 and SSM) will continue to be progressively delivered to potential offtake parties to advance commercial discussions.
