85m of 80% Magnetite at Sortekap SODD001, page-77

FMG will do what it needs to with the magnetite.
I know they intend to crush it but to what fine size I do not know.
hopefully they go quite small or the grade will become an issue.
This will be pumped as a slurry to PH.
quite remarkable engineering.
you can use fine/powdery ore in blast furnaces, you just have to sinter it first.
Which means you need a nucleating ore (harder) to begin the process.
also things like CaCO3 for flux.
Whyalla has shut down multiple times
Pure magnetite companies struggle with low iron ore prices.
No they will be looking for Cu/Ni/Au and Pd

@ Inkblot, any other Producing mines running magnetite out of primary Cu deposits?
Very intrigued what companies do this.
