How Is Iron Transported To Processing Plant

Dust suppression in iron ore processing plants

Handling taconite pellets produces dust. As the pellets are transported, they abrade and produce a fine material that represents a concern for airborne dust. Pellet-breakdown studies revealed that as much as 43% (by weight) of the fine particles were 10 μm in diameter and smaller (material regulated by the U.S. Environmental Protection Agency). This is a …
