Taconite

To process taconite, the ore is ground into a fine powder, the magnetite is separated from the gangue by strong magnets, and the powdered iron concentrate is combined with a binder such as bentonite clay and limestone as a flux As a last step, it is rolled into pellets about 10 millimeters in diameter that contain about 65% iron The pellets are fired at a very high temperature to harThe six taconite plants are projected to produce a total of about 387 million tons of iron ore pellets for the year, according to the Minnesota Department of Iron ore pellet production rebounds in 2021 BusinessNorth

Iron Ore Processing, General

Increasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, mainly the utilization of magnetite and taconite (Taconite is a rock whose iron content, commonly present as nely dispersed magnetite, is generally 25–30%)Taconite mining at this operation includes the following processes: rock drilling/blasting, crushing coarse ore, grinding of the grains (122 cm in diameter), concentrating the iron content, andTaconite mining and processing in the US Download Table

Application of Vertimill fine grinding technology at Hibbing Taconite Company enabled processing of lower grade ores and increased the concentrate production (Pforr, 2001) New hematite/goethite ore types now being exploited are also slowly trending downward in grade and in the longer term will require more processing And yet, the Mesabi Iron Range produces just shy of 40 million tons of iron ore, less than 2%of the world’s total and yet between 7585% of what America uses to make its domestic steel supply That surprising gap tells a story of mining’s future Newer steel mills use recycled steel and specialized ores, not taconiteHope for the Iron Range economy, but we must put the past
