At the Itakpe iron ore mine, the ratio of waste to ore is 4 1. The ratio of tailings to concentrate is commonly very high, generally around 200 1 . For instance, it has been reported that in Western Australia, on average, the production of 1 tonne of iron ore results in the generation of 2 tonnes of iron ore.
The main source of magnetite (Fe2+Fe3+2O4) is magnetite-bearing banded iron formations (BIF) and the key economic parameters for magnetite ore being economic are the crystallinity of the magnetite, the grade of the iron within the banded iron formation host rock and the contaminant elements, which exist within the magnetite concentrate. Occasionally granite and ultrapotassic igneous rocks.

Magnetite. Magnetite is strongly magnetic. It was used by the ancient Chinese to make the first magnetic compasses. The chemical formula is Fe 3 O 4, commonly called ferrous-ferric oxide, and is valuable as an iron ore. Magnetite reacts with oxygen to produce hematite, another iron ore. In crystalline form magnetite is usually octahedral.
Phases of the ore. The iron content of the ore depends on the relative proportion of iron-bearing minerals magnetite (Fe 3 O 4, 72.4 wt Fe), hematite (Fe 2 O 3, 69.9 wt Fe) and goethite (FeO(OH), 59.9 wt Fe). Goethite has the highest amount of impurities and water, and water release during.
Hard iron ore on the Marquette Range consists of nearly pure masses of specularite, magnetite, or martite and occurs near the unconformable contact of the Negaunee Iron-Formation with the overlying Goodrich Quartzite. Most ore is in an upper jaspilite unit of the Negaunee, but some orebodies are entirely within the basal part of the Good-rich.
Iron Ore in General Iron ore is a mineral substance which will yield metallic iron (Fe) at a profit. 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. Almost all iron ore (98 ) is used in steelmaking. Iron ore is mined in about 50.

Iron processing - iron processing - Ores Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is.
