Hi Earnie,
I like the sound of that, more heat produced by the ilmenite generated means lower fuel cost. So far the only variation from expected performance is it's more efficient than was calcualted. A fairy tale project start, the BHP engineer must be pinching themselves in disbelief, you rarely get such a smooth scaleup in any project.
Just shows you how robust the process is, an exceptionally good sign.
Cheers
Seik
