History Of The Iron Ore Trade The Cleveland Memory Project
history of the iron ore trade. this brief history appeared in the 1910 annual report of the lake carriers association. the iron ore trade is, of course, the trade of the great lakes, but it was not always so. the premier trade for so many years was grain, then lumber took first place, giving way subsequently to coal.the iron ore shown to the right was excavated from Sk gar, a viking-age iron-making site in iceland. the larger piece is about in the long dimension. sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smelt.
