Iron Mining Process
The iron ore is separated from the taconite using magnetism. The remaining rock is waste material and is dumped into tailings basins. The taconite powder with the iron in it is called concentrate. ... The balls are then dried and heated until they are white hot. The balls become hard as they cool. The finished product is taconite pellets. Steel
