These resources feature Taconite ore similar to that mined in the Mesabi Range in Minnesota, USA, a mainstay of supply to the North American steel industry since the mid1950s. Processing into highgrade iron ore pellets is based on wellproven and established flowsheet designs. The Millennium Iron Range. The Taconite Project: LabMag and KéMag
Taconite is a lowgrade magnetic iron ore. When highgrade iron ore was plentiful, taconite was considered a waste rock and was not used. But as the supply of highgrade iron ore decreased, the mining industry began to view taconite as a resource. Eventually a process was developed to create taconite pellets by concentrating the low grade ore ...

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 nonamphibole 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 ...

Taconite Ore Processing Mining Equipment. Liberation is the first step in processing crude taconite ore and consists mostly of crushing and grinding. The ore must be ground to a particle size sufficiently close to the grain size of the ironbearing mineral to allow for a high degree of mineral liberation.
Taconite composition varies widely from place to place, but it generally is divided into magnetic taconite, mostly on the East Range extending nonuniformly to the west of Hibbing, and the non ...
EPA prepared these profiles to enhance and update its understanding of the mining industry and to support mining program development by the states. EPA believes the profiles represent current environmental management practices as described in the literature. Each profile addresses extraction and beneficiation of ores.
