Iron Ore Processing, General
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, mainly the utilization of magnetite and taconite. (Taconite is a rock whose iron content, commonly present as nely dispersed magnetite, is generally 25–30%).

Magnetic separation is the most efficient separation method of these technologies. Modern magnetic separators are capable of processing up to 500 t ore/h per unit at a very low operating cost (0.3–0.5 kWh power and 2 m 3 recyclable water/t feed ore). Flotation has the advantage of good selectivity, but it often has much higher …

Iron ore magnetite processing
Iron ore magnetite processing (LIMS, MIMS, WHIMS, Davis Tubes) The increased worldwide demand for steel in recent decades has led to an increase in the exploitation of magnetite iron ore deposits as an alternative to hematite DSO ores. Magnetite concentrate is a higher-grade product than hematite and very desirable as a smelter feed.

Optimising Western Australia Magnetite Circuit Design
Reverese silica flotation is usually seen as a last resort when processing magnetite as there is a certainty that magnetite will be lost to tails. The finisher magnetic separators will have rejected all liberated silica (except for silica slimes that follow the water in the process) ahead of flotation.

Iron Ore Processing, General | SpringerLink
The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.
