Domestic taconite is mined from open pits because most commercial ore bodies lie close to the surface and their lateral dimensions are large. Mining activities involve overburden removal, drilling, blasting, and removal of waste rock and crude taconite from the open-pit (EPA, 2001). DRAFT 2-2 Figure 2-1.

A taconite iron ore processing facility separates and concentrates iron ore from taconite, a low-grade iron ore, and produces taconite pellets, which are approximately 60 percent iron and about ½ inch in diameter. These pellets are then utilized, mainly, in blast furnaces making iron and steel and in the cement industry. Rule History

The rotating labyrinth ring carries a V-ring seal that seals against the stationary labyrinth ring. The V-ring seal blocks contaminants from entering the bearing housing and aids the purging of contamination ...

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 operations in a changing global …

Iron mining shifted to taconite pellet production in the 1950's. Amounts of taconite pellets processed by individual mining operations are also summarized by Reed 56 and updated (Cliffs, Annual Reports).

In winter, when the Soo Locks are shut down, taconite pellets move out of the mining region by rail to the port in Escanaba, which is open to shipping year-round. The first load of iron ore through the Soo Locks amounted to 132 tons in August 1855. Total ore tonnage that year was 1,447. During the 1860 shipping season 120,000 tons of ore passed ...

Objective: To examine the association between employment duration, elongate mineral particle (EMP) exposure, silica exposure and the risk of lung cancer in the taconite mining industry. Methods: We conducted a nested case-control study of lung cancer within a cohort of Minnesota taconite iron mining workers employed by any of the mining companies in operation in 1983.

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
