Basically the taconite process involves crushing the rock to a fine-grain size, then mechanically removing the iron minerals from the waste material. Magnetite can be removed from the siliceous waste materials by large electromagnets. Hematite requires a more sophisticated process for concentration.

What Is Taconite | Taconite Features


Taconite definition gives information about the Formation of Taconite and its composition.The composition of Taconite can be further divided into mineral and compound content. The mineral content of Taconite rock includes Hematite, Magnetite, Quartz and The compound content of Taconite rock includes Fe, Iron(III) Oxide, Silicon Dioxide.

SUPERIOR FE DEPOSITS (MODEL 34a; Cannon, 1986)


Processing taconite to concentrate iron minerals produces large volumes of fine-grained tailings that must be permanently stored. The tailings consist of quartz, a variety of silicate minerals, some of which may be fibrous, iron carbonate minerals, and iron oxide minerals. Potential environmental concerns related to tailings include:

Liberation Characteristics of Taconite Plant Feeds


effective mineral grain size, volumetric grade, and dilution ratio. Effective grain size refers to particle size below which a portion of the valuable mineral particles appears to be liberated. This parameter is determined by model fit to test data, and it was shown that it correlated well with the microscopic measurement of grain

Iron ore - Wikipedia


Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.

Implications of Mineralogy, Grain Size and Texture on ...


The Lake Superior Region has been a producer of iron ore for over 150 years. Early mining operations concentrated on direct shipping ores, which are the result of post-depositional upgrading principally by deep weathering. As direct shipping ore reserves became depleted, the focus changed to the production of iron ore pellets from taconite. The post-depositional...

Prediction of carbonate mineralogy and carbonate mineral chemistry is an important goal of ore characterisation for pelletising properties. Contact metamorphism causes changes in mineralogy and grain size (Klein, 1973; Gunderson and Schwartz, 1962). Increasing the grain size of magnetite should improve its liberation characteristics.

Taconite - Wikipedia


Taconite (IPA: ['tækənaɪt]) is a variety of iron formation, an iron-bearing (over 15% iron) sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate.The name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) – son of Newton Horace Winchell, the Minnesota State Geologist – during their pioneering investigations of the Precambrian Biwabik ...
