Cost Curves
----------------
The Iron Ore cost curves have been updated to incorporate these model revisions.
The curves are for 1998 to 2004 and contain cost rankings for each iron ore saleable product in US cents/mtu and for tons of ROM ore.

Model Productivity Factors
----------------------------------
The iron ore models now contain adjustment factors in the Edit sheet that allow users
to change mine and mill labour productivity and consumables usage rates, independently
of the flowsheet and other settings built into the models.
This makes the models even more flexible since users can now "tune" the models to
match known actual performance or test various scenarios and look at sensitivities.
These adjustment factors are now incorporated into all minecost models.
