interesting spot there MP

I've thought for a long time that CSD would be able to reverse float the silica ( the managed that in the PFS), then separate magnetically the magnetite easily enough ( with a great big electromagnet ) from the resulting slurry leaving a fairly concentrated tin ore which would be easier to value add and cheaper to ship ( lower volume) if processed locally ( bigger profit)

So back to positive thinking - Stannous Oxide covers a multitude of sins as far as a term is concerned. Stannous oxide occurs naturally as casserite which is what CSD will produce even in concentrate form.

However SnO is mentioned not SnO2 and this is a different kettle of fish which from my reading implies roasting / fuming locally from that statement. It could be a good thing or it could be a typo.

I'll find time to do some maths ( when I'm not at work) to get a rough idea of expected kg/hour needed to gain 3000 t of tin if the ore is 'debulked' as above
