Interesting article.
KRR is one miner I'm aware of with significant amounts of aluminium in it's ore body.
I don't recall seeing anything re aluminium or phosphorus in the Mt Peake ore body but if there is either of these in significant amounts hopefully all the sampling, tweaking and adjusting that's been going on means the company will have a good handle on it once in production.

"Vanadium is rarely found in the earth on its own. It likes to pair up with silicone, phosphorous, aluminum and even titanium.
Within a deposit, it is found with varying levels of these other elements. That’s a problem for smelters.
If the vanadium isn’t treated with the right chemical cocktail before smelting, the results can be explosive.
Michael told me the story of major miners blowing up smelters because a batch of vanadium had high levels of aluminum and phosphorus.
Most miners only need a couple of samples of ore to find the best way to process. The entire process needs little tweaking once in production.
But vanadium miners can find themselves sampling, testing and experimenting with endless combinations in some ore bodies. It’s the kind of process that will set back operations and see cost overruns."
