Iron is the most abundant rock
forming element and composes about 5 % of the
Earth's Crust. Astrophysical and seismic evidence indicate that iron is
even more abundant in the interior of the Earth and has apparently
combined with nickel to make up the bulk of the planet's core.
inner core of the Earth is believed to be a solid iron-nickel alloy.
Iron-nickel meteorites are believed to represent the earliest material
formed at the beginning of the universe. Studies show that there is
considerable iron in the stars and terrestrial planets: Mars, the "Red
Planet," is red due to the iron oxides in its crust.
Hematite is iron oxide (Fe2O3). Hematite deposits are
mostly sedimentary in origin, such as the banded iron formations (BIFs).
BIFs consist of alternating
layers of chert (a variety of the mineral quartz), hematite and
magnetite. They are found throughout the world and are the most
important iron ore in the world today. Their formation is not fully
understood, though it is known that they formed by the chemical
precipitation of iron from shallow seas about 1.8-1.6 billion years ago,
during the Proterozoic Eon.
About 98% of iron ore is used to make steel - one of the greatest inventions and most useful materials ever created. While the other uses for iron ore and iron are only a very small amount of the consumption, they provide excellent examples of the ingenuity and the multitude of uses that man can create from our natural resources. Powdered iron: used in metallurgy products, magnets, high-frequency cores, auto parts, catalyst. Radioactive iron (iron 59): in medicine, tracer element in biochemical and metallurgical research. Iron blue: in paints, printing inks, plastics, cosmetics (eye shadow), artist colors, laundry blue, paper dyeing, fertilizer ingredient, baked enamel finishes for autos and appliances, industrial finishes. Black iron oxide: as pigment, in polishing compounds, metallurgy, medicine, magnetic inks, in ferrites for electronics industry.
Consumption of iron ore and agglomerates at U.S. iron and steel
plants, by type of product
In 1988, the first commercial Corex plant was commissioned at Pretoria in the Republic of South Africa. Many of the technical problems associated with the startup of this 300,000- metric-ton-per-year demonstration plant have since been solved, and several steel companies are now considering building much larger units in the United States and Western Europe. The proposed Corex plants are still significantly smaller than existing blast furnaces but can be brought up to full operation much quicker with less cost. A key feature of the Corex process is that it uses untreated raw coal in place of coke. The ability to operate without coke gives the Corex plant two environmental advantages over the conventional blast furnace. First, because coke ovens are not needed, all of the problems associated with the generation of benzene and other coal tar byproducts are eliminated. Second, the dust problems associated with blast furnaces are also eliminated because the offgas is used as fuel. Joint COREX and DRI plants are now on the drawing board, with the offgas from the Corex plant being used to fuel the adjoining DRI plant. Direct steelmaking, a much more revolutionary process, is still in the early stages of development.
Substitutes and Alternative Sources
Simply there is no substitute for iron, iron ores are not the only materials from which iron and steel products are made. Very little scrap iron is recycled, but large quantities of scrap steel are recycled. Steel's overall recycling rate of more than 67% is far higher than that of any other recycled material, capturing more than 1-1/4 times as much tonnage as all other materials combined. Some steel is produced from the recycling of scrap iron, though the total amount is considered to be insignificant now. If the economy of steel production and consumption changes, it may become more cost-effective to recycle iron than to produce new from raw ore.Iron and steel face continual competition with lighter materials in the motor vehicle industry; from aluminum, concrete, and wood in construction uses; and from aluminum, glass, paper, and plastics for containers.
Note: We are proud to say we are one of fewer companies in Tanzania to pioneer towards the Research concerning the Iron Ores Deposits in Tanzania. We own entire Mountain with Iron Ore deposits, though our production is still low due to limited Exploration Machinery Units etc., But yet still we can produce at least 5000 tons of Iron Ore monthly. For Serious Buyers from Potential Companies we do invite them to view our Iron Ore Deposits here in Tanzania.
SOURCES FOR THIS
IRON ORE DEPOSITS IN TANZANIA
Iron Deposits are also found in Tanzania in about 3 different regions, Its found in Morogoro, Mbeya - Kyela and other 2 regions in Tanzania. In this other 2 regions Our company owns this Mines and we do posses the PR for Mining the Iron Ore.
The Iron Ore found in this area, Its Iron Purity is 52% with TiO2 - Standing at 11%.This data proves that the content of Iron and Titania is typical of the Fe - Ti Ores associated with anorthosites and gabbroic rocks within the Proterozoic belts of the world e.g Tanzania Iron deposit and that of Sweden. Millions of Tons lie underneath unearthed within this 3 regions in Tanzania.
Currently our Mines can produce monthly over 5000 tons of Iron Ore. As the Company we want to Outgrow this Number to reach to 20,000 tons Monthly upwards once the Mines will be full Explored.
