I find this quite good it explains the different types (and the conversions possible):

I believe we only have Laterite, (and no Sulphide) sources of nickel at both Araguaia and Vermelho. At both sites we have Limonite (which is amenable to HPAL, RKEF, or RKEF + nickel matte conversion) and Saprolite (which is amenable to RKEF or RKEF + nickel matte). HPAL produces nickel sulphate + cobalt, RKEF produces ferronickel, matte conversion produces an intermediate product which can be further refined to convert to batteries. Matte conversion is the only way to get from non-limonite ferronickel to nickel suitable for batteries, I believe.
So the difference between Vermelho and Araguaia is the proportion of limonite and saprolite (which are listed on the website on the project pages), I think at Vermelho limonite is like 50% whereas at Araguaia a lot lower percentage. So this makes Vermelho the place to do hpal at all (or not at all) as presumably at Arauguaia it isn't cost effective to separate the limonite and process it through HPAL as there isn't enough of it.
Ferronickel and NPI (nickel pig iron) are classed as class 2 nickel which typically also trades at a discount to the main LME nickel price which I think is for class 1/ refined nickel. If nickel sulphate is also trading at a discount to pure nickel then I think it is because of oversupply by Indo/China. I think the discount/premium is very volatile as it was at a premium during/pre covid. I asked this question on the last but one investor presentation because I was concerned that with the flooding of 'cheap' hpal projects in Indo Vermelho might be up against competition where you don't want to be competing on a difficult build, high capex project against an oversupply scenario. The latest presentation confirms they are thinking carefully over the route.
For me the geo-political situation is the one that will be key - will we see China 'hoard' its supplies and will the west prefer western producers and then which way will Brazil go. It seems to me that with the high ESG Horizonte are specifically targetting western consumption of the produced nickel which, looking ahead, is probably the way to go even if there is some extra ESG cost of getting there.
If any of the above are wrong please correct, I'm not a chemist!
