Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various ...
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. In fact, it was not until 1888 that iron ore became the dominant trade …

During the last ten years great strides have been made, on the Mesabi range, in the practice of beneficiating low grade iron ore material. By beneficiation is meant all methods of removing impurities, and raising the iron content to a point where it can be sold in open market, the principal impurities being silica and moisture. The general processes to which low grade iron ores are amenable ...
