Air Cure Dust Control equipment at a Taconite (Iron)mining operation. Taconite (Iron) Mining Application. Taconite dust is a challenging application, especially outdoors in northern Minnesota, where besides the renowned abrasiveness and very fine particulate of taconite, the equipment must with-stand very cold temperatures.
taconite crushing equipment,taconite mining crusher XSM. Taconite is a variety of iron formation, an iron-bearing (> 15% iron) sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate.
Iron Ore/Taconite. In the ironmaking process, the blast furnace or direct-reduced iron (DRI) plant will typically use iron ore pellets, which are created when iron ore fines are agglomerated and heated using a rotary kiln. Many producers use a traveling grate and rotary kiln to heat the pellets to temperatures as high as 800°C to 900°C in the

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
