To process taconite, the ore is ground into a fine powder, the magnetite is separated from the gangue by strong magnets, and the powdered iron concentrate is combined with a binder such as bentonite clay and limestone as a flux. As a last step, it is rolled into pellets about 10 millimeters in diameter that contain about 65% iron. The pellets are fired at a very high temperature to harden them and make them durable. This is to ensure that the blast furnacecharge remains porous enough to allow heated gas to pass throu

Taconite is a hard, banded, low-grade ore, and is the predominant iron ore remaining in the United States. Ninety-nine percent of the crude iron ore produced in the United States is taconite. If magnetite is the principal iron mineral, the rock is


Taconite is mined from the Mesabi Iron Range, near Hibbing, MN. Then it is processed into pellets and moved by train--or on ore boats from Duluth--to ports and steel mills around the Great Lakes region. Taconite process photos courtesy American Iron Ore Association and Hibbing Taconite.

After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry. To make these pellets, the hard taconite ore is blasted and then ground down with water to a fine powder. The fine iron rich particles, mostly of magnetite are extracted from the powder by use of magnetism.

Edward Wilson Davis (May 8, 1888 December 3, 1973) was an American engineer and inventor famous for pioneering early research into taconite.As a researcher at the University of Minnesota, Davis developed an engineering process to economically extract iron ore from hard taconite rocks, making taconite valuable as iron ore for the iron and steel industries.

Iron Mining Process. The taconite pellets are loaded into ore ships. These ships sail on the Great Lakes to Gary, Indiana, Cleveland, Ohio and other steel-making towns. The taconite pellets are brought to the steel mills to be melted down into steel.

These resources feature Taconite ore similar to that mined in the Mesabi Range in Minnesota, USA, a mainstay of supply to the North American steel industry since the mid-1950s. Processing into high-grade iron ore pellets is based on well-proven and established flowsheet designs. The Millennium Iron Range. The Taconite Project: LabMag and KéMag

In 1955, the Reserve Mining Company began operating in Silver Bay, Minnesota. The processing plant for Reserve’s taconite mine was situated right off the shore of Lake Superior, but in the 25 years that the company was operating, the distance between the processing plant and water’s edge slowly grew.

Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive.

Since there were many accessible deposits of natural ore with iron contents closer to 60 percent of the rock, taconite was at first passed over in favor of ore that could be shipped directly to smelters without processing. Taconite was officially documented on the Mesabi Iron Range years before mineable natural ore was found near Mountain Iron.

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 profitably extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves were diminished, taconite became an alternative source of iron that allowed the Iron Range to continue mining operations in a changing

Typically, mill tailings range from sand to silt-clay in particle size (40 to 90 percent passing a 0.075 mm (No. 200) sieve), depending on the degree of processing needed to recover the ore. The basic mineral processing techniques involved in the milling or concentrating of ore are crushing, then separation of the ore from the impurities.
