A crucial step in mineral processing – and in Minnesota's iron ore processing – is comminution, a process of crushing and grinding. Large rocks must first be crushed and then ground down to tiny particles to expose the valuable or desired minerals so they can be separated from the waste rock. The prevalence of low-grade and complex ores make …

Iron Ore Pellets are then used in the production of steel. Pellets are usually preferred instead of raw Iron Ore because it allows for maximum utilization of iron ore. This is important since iron ore reserves are depleting globally. So methods like pelletizing and sintering ensure that there is no waste of this precious resource.

Iron ore mining in the Birmingham District followed the ups and downs of iron and steel production. Active mining stopped in 1975. After that, cheaper imported ores were used until the iron and steel industry was mostly shut down. It is estimated that from 1840 to 1975, 375 million short tons of iron ore were produced in the Birmingham District.

Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal.
