Good test results,,,,,,,,,
o Pyrometallurgical pilot with Metso’s Grate Kiln technology complete and has confirmed its suitability for vanadium, with extractions of up to 94.9% achieved. o Hydrometallurgical testwork has demonstrated the effectiveness of the ammonium polyvanadate precipitation process, leading to a high purity product. o Characterisation and testwork of variability samples has demonstrated high iron grades of over 60% achievable in concentrates from southern ore blocks. o Benchscale reduction-roast testwork has demonstrated that the FeTi coproduct stream can be upgraded to 66% iron, with further work underway using alternative reductants such as green hydrogen.
