Raw iron ore was shipped to the plant by train from another location. The material was crushed and milled in a multiple step process. Iron was separated from the processed taconite ore by magnetic separation and the iron rich concentrate was processed for shipping by adding a binder, and rolled to form green pellets.

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.
