The process of enriching taconite ore involved grinding the ore to remove gangues and upgrading the iron ore (, an ore beneficiation process). The resultant high grade ore is in the form of fine particles, as small as mm or less, which are not suitable for sintering. This issue led to the development of the pelletizing process.

Taconite is a flintlike type of rock containing lowgrade iron ore. Vast reserves of taconite, with iron concentrations of 3050%, were discovered in 1870 near presentday Babbitt, on the Mesabi Iron Range. However these deposits were passed over in favor of mining existing high grade iron ore formations, because extracting the pure iron from ...
