Bushveld Minerals has second option to process vanadium at flagship


Metallurgical test work has identified a second way of processing the valuable vanadium by-product at Bushveld Minerals’ (LON:BMN) flagship iron ore project in South Africa.

Extraction tests for a vanadium pentoxide product yielded recoveries between 79%-86% using a salt roast process.

Overall vanadium recovery was estimated at 74%, including downstream precipitation of the vanadate solution, which was in line with previous modelling, Bushveld said.

As well as salt roasting by leaching (to produce vanadium pentoxide and, if further beneficiated, ferrovanadium), Bushveld has previously tested a second option of smelting the ore to produce a high-grade vanadium slag and a pig iron product.

Fortune Mojapelo, Bushveld Minerals’ chief executive, said: "Having reported the results of the modelling exercise undertaken on the smelting processing route last week, we are pleased that results from the salt roast route, including lab-scale vanadium extraction, prove we have two viable processing options to consider.

Both of these processes are proven and in operation using ore similar to that within the MML, which is obviously encouraging.

“We look forward to building on these results in our Scoping Study which is underway and expected out in the coming months."
