11.23 Taconite Ore Processing

(Refer to Table 11.23-1 for Source Classification Codes) Crude ores in which most of the recoverable iron is magnetite (or, in rare cases, maghemite) are normally concentrated by magnetic separation. The crude ore may contain 30 to 35 percent total iron by assay, but theoretically only about 75 percent of this is recoverable magnetite. The remaining iron is discarded with the gangue.

2018-06-04  Davis’s low intensity magnetic separation process worked well on taconite’s magnetite ores, but those magnetite reserves will eventually be depleted. What’s next? NRRI is developing a process that recovers two other valuable iron oxide minerals -- hematite and goethite -- using a natural pH flotation process. Bench scale testing shows ...

Mercury Transport in Taconite Processing Facilities: (II ...

followed by magnetic separation to release the primary ore mineral, magnetite, from the more abundant non-magnetic gangue minerals (silicates, carbonates, hematite, goethite). Because magnetic separation is the primary means used to concentrate iron from taconite ore, experiments were conducted to determine how mercury partitions between magnetic and non-magnetic minerals.

Energy and Environmental Profile of the U.S. Mining Industry 4

Using the magnetic properties of magnetite, magnetic-separation is the principal choice for taconite. Hematite ores are concentrated using conventional flotation. The concentrate is then filtered to remove water and passed to pelletizing and sintering operations.

11.23 Taconite Ore Processing

magnetite is the principal iron mineral, the rock is called magnetic taconite; if hematite is the principal iron mineral, the rock is called hematic taconite. About 98 percent of the demand for taconite comes from the iron and steel industry. The remaining 2 percent comes mostly from the cement industry but also from manufacturers of heavy-medium materials, pigments, ballast, agricultural ...
