Though taconite was identified as an ironbearing rock on the Iron Ranges of northern Minnesota long before the 1950s, it wasn't until then that it was extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves diminished, taconite became an alternative source of iron that allowed the Iron Range to continue mining operations in a changing global economy.

PROCESS DESCRIPTION2'6 Processing of taconite consists of crushing and grinding the ore to liberate ironbearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 21.

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.
