Serious question re/ AVL and TMT, page-142

Hi @Gollada, Drunknvegan is correct. From memory KRR got their *Mass Recovery up to only ~16% [Ref.] at the end of their studies, which means processing a lot more rock. Does the high V recovery in the concentrate compensate for this? Might be a question for TVN who are buying the deposit. Some deposits have reported mass recoveries as low as 10%, which is uneconomical. The normal is 50/50 (Mt. Peake/Yarrabubba etc.) AVL have reported average mass recoveries of 57% but they've had to tweak their (patented) processing to account for the high oxidation levels at surface (especially in those northern blocks). As the rock is de-magnetised under extreme weathering conditions mining will commence in the southern blocks (down Yarra way) where the fresh ore is closer to surface, and blended with the weathered ores to improve concentrate recoveries. We won't know until real-world production to see how their blending strategy and recoveries really fare. Despite this it would be fair to say the Ga-banintha deposit is still the best vanadium‑titanium magnetite deposit in Australia, and definitely globally significant.


*Mass Recovery (or weight/yield recovery) is critical in the evaluation of magnetite deposits. Mass Recovery is the percentage of the head (feed) mineralisation by weight that is recoverable by concentration processes.
