Pelletizing - Wikipedia
Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...

Refining (metallurgy) - Wikipedia
The product of the blast furnace is pig iron, which contains 4–5% carbon and usually some silicon.To produce a forgeable product a further process was needed, usually described as fining, rather than refining.From the 16th century, this was undertaken in a finery forge.At the end of the 18th century, this began to be replaced by puddling (in a puddling furnace), which was in turn gradually ...

Yoopera - Iron Ore Collection
Our Iron Ore Collection is made from a naturally-occurring iron oxide, which is widely found across Michigan's Upper Peninsula. In it's natural state, it's known as Fe2O3, and later separated out as a biproduct in the process of turning iron ore to steel. However, when you see it polished and in its final form, you'll never think of it as a castaway.

Froth flotation - Wikipedia
His "Bradford Ore Separator," patented 1853 and subsequently improved, was used to concentrate iron, copper and lead-zinc ores by specific gravity, but lost some of the metal as float off the concentration process. The 1886 patent was to capture this "float" using surface tension, the first of the skin-flotation process patents that was eclipsed by oil froth flotation. It is .

10/03/2016· Iron ore deposits in India can be broadly classified as aluminous and siliceous. Although most of the Indian ores are highly aluminous in nature, in some mines, silica content is even higher than the alumina content. It is often seen that iron ores available in the southern part of the country are siliceous in nature, whereas the iron ores from the eastern and central parts .

Iron processing - Ores | Britannica
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 ...

Iron processing - Iron making | Britannica
Iron processing - Iron processing - Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
