Overview | Labrador Iron Ore
Ground ore is then concentrated in the spiral plant using gravity spirals to increase the iron content from 38% to approximately 65 - 66%. A magnetic separation plant extracts magnetite from the spiral plant's tailings, while a hematite recovery plant recovers fine particles of hematite from the tailings of the magnetic separation plant.
Magnetite | Common Minerals
Magnetite is a black, opaque, magnetic mineral that leaves a black streak when rubbed across a hard rough surface. It is one of the most abundant metal oxides, and its crystal structure contains both the ferrous (Fe+2) and ferric (Fe+3) forms of iron ions. A complex pattern of electrons between the two forms of iron is the source of its ...
