Taconite is a low-grade magnetic iron ore. When high-grade iron ore was plentiful, taconite was considered a waste rock and was not used. But as the supply of high-grade iron ore …

A taconite iron ore processing facility separates and concentrates iron ore from taconite, a low-grade iron ore, and produces taconite pellets, which are approximately 60 percent iron and about ½ inch in diameter. These pellets are then utilized, mainly, in blast furnaces making iron and steel and in the cement industry. Rule History

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, or the taconite is transported if further away. Crushing At the processing plant, the taconite is crushed into very small pieces by rock crushing machines.

existing mine pits in the area and open pit mining operations to remove ore and waste rock. Waste rock will be stockpiled near the mine pit and ore will be hauled to the crusher with further processing in the concentrator and pellet plant. Tailings from the concentrator will be discharged to the existing Butler Taconite Stage I Tailings Basin.

United Taconite operates the Thunderbird Mine and the Fairlane taconite production plant, each so named because the facilities were once owned by Ford Motor Co. After the blast, a huge excavator (shovel) will continually load massive haul trucks that bring the rock to the crusher. ... At United Taconite, the crusher is located at the ...

In 1947 Pickands Mather announced that Erie would build a demonstration plant to make taconite ore into pellets — three tons of taconite to make one ton of pellets and two tons of tailings. And the plant would be massive. Erie opened in 1957. The total cost seemed astronomical — $300 million — and it would take four years.

Production involves mining, crushing, grinding, concentrating, pelletizing and fire-hardening of pellets. All current production, and probably all future production in the Lake Superior region will be from taconite. A common feature of all taconite mines—they're big. Includes large open-pit, mill, waste piles, and tailings basins.

Taconite, the principal iron ore mined in the United States, has a low (20 percent to 30 percent) iron (Fe) content and is found in hard, fine-grained, banded iron formations. The main taconite iron ore deposits are located near Lake Superior in Minnesota (Mesabi Iron Range) and Michigan (Marquette Iron Range). The taconite mining operations in ...

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.
