Coking coal's turn to rally The iron ore price has well and truly rebounded from $US86 a tonne last September to $US153 a tonne. But its sister product in steelmaking, coking coal, has been left at the starting stalls, for the time being at least. From its average in (calendar) 2011 of around $US290 a tonne, coking coal retreated to an average of about $US210 a tonne last year.
