Iron ore taconite pellets were obtained from a processing facility located in the Midwest United States, identified as "Plant D". The sample, received in a 208 liter (55 gal) drum, was split into twelve 19 liter (5 gal) buckets each weighing approximately 23 kg (50 lb), using coning and splitting techniques.
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per …

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 …

Each taconite iron ore processing plant is located directly proximate to its own mining source. Transportation costs of procuring raw materials from other locations are prohibitive. A plant has no access to the raw ore used by another plant and, consequently, could not duplicate the mercury emissions performance of the other plant. ...
Though taconite was identified as an iron-bearing 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 …
This modern process for extracting iron ore from taconite and refining concentrate into pellets is a direct result of Dr. Davis' research funded by the IRRRB: First, holes are drilled and the taconite ore is blasted out of the ground. It is transported to the processing plant in huge trucks that can hold up to 240 tons of taconite.
Taaconite is a low-grade iron ore containing 20- to 25-percent iron; 99% of the crude iron ore produced in the United States is taconite, according to the US EPA. Taconite iron ore processing plants separate and concentrate iron ore from taconite to produce taconite pellets, which are 60- to 65-percent iron.
