taconite ore ag milling processing

11.23 Taconite Ore Processing

Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.

Taconite Wikipedia

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.

Commercialization of Taconite MNopedia

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.

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 At the processing plant, the taconite is crushed into very small pieces by rock crushing machines.

How innovation saved the Iron Range Natural Resources

Jun 04, 2018 Close on Reserve’s heels, Erie Taconite began production of pellets at Hoyt Lakes in 1957. In 1960, Reserve Mining expanded the Silver Bay plant, increasing annual capacity by 50 percent, to 9 million tons. (Davis got the important news while getting his hair cut in town.) In 1961 and 1962, U.S. Steel opened taconite plants in Quebec and Wyoming.

More efficient grinding for Iron Range industries

Jun 03, 2020 Traditional taconite pellet-making processes use a rod mill to get the rock to the consistency of coarse sand, and a ball mill to grind the rock into a fine powder. This technology is still in use on Minnesota’s Iron Range by some facilities. A taconite plant may have as many as 18 rod mills with one rod alone weighing as much as 500 pounds.

Commercialization of Taconite MNopedia

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
