Technology Metals test work improves purity of vanadium further
Date: Dec 12, 2018
The definitive feasibility study is on track for delivery in the June quarter of 2019.
Technology Metals Australia Ltd (ASX:TMT) has received results from more metallurgical test work on samples from the Gabanintha Vanadium Project in Western Australia.
Refinement work on a sub-sample delivered a vanadium pentoxide (V2O5) product with a purity in excess of 99.7%.
The V2O5 product came from an ammonium metavanadate precipitate that recovered over 98% of vanadium from a leach solution.
This high purity further confirms the suitability of Gabanintha vanadium product for the speciality chemical, battery and aeronautical industries.
Preliminary base metal recovery test work delivered highly encouraging flotation concentrates with a combined base metal content of 10% to 15%, containing up to 2.31% cobalt, 4.47% nickel and 9.50% copper.
This test work focused on the non-magnetic (tailings) fraction from the magnetic separation process.
Notably, significant scope exists to optimise the base metal recovery into a concentrate product.
