Taconite is a low-grade iron ore. Originally thought to be of little value, taconite was considered overburden (waste) in the days when high grade iron ore was mined. The iron content, magnetite, is only 20- 30% compared to 50 - 60 % iron content in red ore. Red ore is also referred to as direct shipped ore because it can be shipped …

• EPA issued the initial air toxics standards for Taconite Iron Ore Processing on October 30, 2003. The rule applies to major source facilities engaged in separating and concentrating iron ore from taconite (a low-grade iron ore) to produce taconite pellets. These taconite pellets are then used as feed in blast furnaces to produce steel.

The taconite pieces are scooped up by electric shovels. Each shovel can hold up to 85 tons of rock. The shovels place the taconite into giant dump trucks. These trucks are as big as a house and hold up to 240 tons of taconite. The trucks take the taconite directly to the processing plant, or the taconite is transported if further away. Crushing
And Iron Range taconite plant owners Cleveland-Cliffs and U.S. Steel are both increasing production of a new type of iron pellet that does not require coal-powered blast furnaces to process into steel. Electricity can be used instead, meaning a rail connection to coal mines may no longer be necessary for processing the raw material …
