11.23 Taconite Ore Processing. Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.

Though taconite was identified as an iron-bearing rock on the Iron Ranges of northern Minnesota long before the 1950s, it wasn't until then that it was profitably extracted, processed, and shipped to steel mills on the Great Lakes. As natural ore reserves were diminished, taconite became an alternative source of iron that allowed the Iron Range to continue mining operations in a changing ...

Pilot plant evaluation of the high pressure roller press has shown that it can be used as an alternative to the rod mill for the comminution of taconite. A series of pilot plant tests were run to compare roller press products to rod mill products in a simulated taconite flowsheet using magnet separation and closed circuit ball milling.

Taconite processing requires a lot of water, and the basin serves as a reservoir for water used in the plant. The basin covers roughly 8,000 acres and is located in the Rainy River watershed and two sub-watersheds within the Rainy system: Sand River to the east of the basin and Dark River to the west.

The taconite pieces are scooped up by electric shovels. Each shovel can hold up to 85 tons of rock! The shovels place the taconite into giant dump trucks. These trucks are as big as a house and hold up to 240 tons of taconite. The trucks take the taconite directly to the processing plant, if it is nearby, or to train cars if it is far away.
