3. Crushing. At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. The rock is mixed with water and ground in rotating mills until it is as fine as powder.

Enhancement of taconite crushing and grinding through
Apr 01, 1997 TACONITE MINING Taconite mining and processing is very costly due to the hardness and abrasiveness of these low grade iron ores. The processing usually involves two stages of crushing and coarse and fine grinding after primary crushing, and the comminution costs per tonne will increase substantially for each downstream stage.

Emission Factor Documentation for AP-42 Taconite Ore
Taconite Ore Processing Final Report Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, Gyratory crushers are generally used for primary crushing, and cone crushers are used for secondary and tertiary fine crushing. Intermediate vibrating screens remove undersize material from the

Comparison of the Primary Grinding of Taconite in a Pilot
Progressive improvements in crusher design, screening efficiency, and operating experience along with the down sizing of many taconite operations has resulted in the ability of some crushing plants to produce a substantially finer product. This finer product opens the possibility of replacing the rods in the rod mill with balls.

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

They're crushing it Mine mesabitribune
Jun 24, 2020 At some iron ore plants, taconite is crushed down to pieces of small rock by primary, secondary and tertiary crushers. Some plants also use autogenous or semi-autogenous crushing, in which rock basically crushes other rock. Then, giant rotating mills which hold massive-size rods and balls, further grind the material.

Dec 18, 2002 Emission units include ore crushers (primary, secondary, and tertiary), screens, conveyors, storage bins, and transfer points. The ore crushing and handling affected source begins where crude taconite iron ore is dumped into the primary crusher and ends where the unfired (green) pellets enter the indurating furnace.
