information about limonite iron
USGS Minerals Information: Iron OreIron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3).. Iron ore is the source of primary iron for the world's iron and steel industries.Iron ore WikipediaChineseIncreasing iron ore demand, coupled with the depletion of highgrade hematite ores in the United States, after World War II led to development of lowergrade iron ore sources, principally the utilization of magnetite and taconite. Ironore mining methods vary by the type of ore being mined.Sources&ensp·&ensp

Limonite has a complex chemical composition. The limonite found in Illinois may be yellow, orange, red, brown, or black, but its streak is always yellowish brown.
Recovering limonite from Australia iron ores by Abstract. Successful recovery of limonite from iron fines was achieved by using flocculationhigh intensity magnetic separation (FIMS) and adding hydrolyzed and causticized flocculants according to the characteristic of iron fines.Limonite: an iron oxide used as pigment and iron oreLimonite has been used as a lowquality iron ore for thousands of years. Commercial mining of limonite as a source of iron is no longer done in areas where reasonable deposits of hematite and magnetite are present or readily imported. Limonite deposits are usually too
