Pure speculation on my part, but I wonder if the cargoes for South Chicago were crushed taconite rock and not iron ore pellets.
First, the vessel passage page for Great Lakes Fleet shows the cargoes as taconite, not as iron ore or iron ore pellets as most other cargoes are listed.
Second, I believe the dock they are unloading at is operated by Ozinga Materials, one of the Chicago area's largest concrete producers.
Third, Minnesota has been quite active in trying to market overburden and tailings from the Mesabi range as construction aggregate. They even have coined the name Mesabi Hard Rock as a marketing name. The aggregates have been used for years for local construction but they are trying to develop new markets.

Again, just a guess, but if it is aggregate, hopefully a new market is developing. I've always thought that the huge waste rock piles on the Marquette Range could be marketed in the Detroit, Toledo and Cleveland areas, but I suspect the profit margin on construction aggregates is quite low.
