Good clarification surebob. Here is a quote from the link you provided.

Iron Ore Costs
We are frequently asked to clarify iron ore cost calculations, as expressed 'per iron unit', or 'per tonne of iron ore'. Accordingly, here is a simple example using figures from the table above, as would have been paid by a European steelmaker purchasing Brazilian iron ore. The Brazil H1 2009 fob price for 67.55% Fe iron ore was ~US cents 101/dmtu (equivalent to $1.01/dmtu) as shown above (dmtu: dry metric tonne unit). The H1 2009 fob European price was thus $68.2/tonne of iron ore (which is $1.01*67.55%). The unit dmtu refers to 1% Fe content, or to price per 10 kg iron unit.
