Customer Reviews | Taconite Aviation

I contacted Taconite Aviation and easily arranged an aerial tour of the iron range. It was spectacular. Pilot Gary Ulman knew all of the history of the different mines and fully explained the operations, past and present. We got the full and complete view of the Iron Range from a professionally flown flight.

A case–control study of mesothelioma in Minnesota iron

Objectives An excess of mesothelioma has been observed in iron ore miners in Northeastern Minnesota. Mining and processing of taconite iron ore generate exposures that include elongate mineral particles (EMPs) of amphibole and non-amphibole origin. We conducted a nested case–control study of mesothelioma in a cohort of 68 737 iron ore miners (haematite and taconite ore miners) to evaluate ...
