The most striking production changes since 1952 are the growth in mine production of agglomerates and the decline in production of direct-shipping ore. In 1952, less than 6 percent of usable ore was agglomerated before shipment, mostly in the form of sinter. Pellets were still in the pilot plant stage. In 1978, more than 80 percent of usable ore will be agglomerated before shipment, practically all in the form of pellets. These changes have resulted from depletion of direct-shipping ores and increasing reliance on taconite.
