2015-9-10 The taconite ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. The six-digit Source Classification Code (SCC) for taconite ore processing is 3-03-023. Table 11.23-1 lists the SCCs for taconite ore processing. Taconite is a hard, banded, low-grade ore, and is ...

2020-6-3 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.

2021-11-12 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 ...

2013-11-8 In the grinding circuit, rod, ball, or autogenous mills grind the taconite down into even smaller uniformed-sized particles. The ore is ground less than 325 mesh, and in some cases less than 500 mesh (45 - 25 microns) to help facilitate the liberation of the iron minerals from the rock. 4.1.2.3 Concentration

2021-10-28 “A taconite plant may have as many as 18 rod mills with one rod alone weighing as much as 500 Ib (227 kg). Tumbling around in the mills with the hard taconite wears away the rods and balls and need to be replaced frequently.” This is a costly and energy-intensive process and the waste rods and balls are a disposal problem, according to NRRI.

2021-9-2 Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines’ autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.
