Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries. The seven largest of these producing countries account for about three-quarters of total world production. Australia and Brazil together dominate the world''s iron ore exports, each having about one-third of total exports.
The product is "pig iron", used in foundries to make a variety of castings such as car engine blocks, and parts for light and heavy machinery. Pig iron is usually remelted and suitably treated to make castings. ''Cast iron'' is therefore more highlyrefined than ''pig iron''.
After cleaning, it is used for a variety of purposes, including heating of the hot blast stoves ["cowpers"], in iron ore agglomeration plants and for electricity generation. The credit for this gas is an important factor in keeping blast furnace operating costs low.
Use of iron ore fines, coke breeze, metallurgical wastes, lime, dolomite for hot metal production Better reducibility and other high temperature properties Increased BF productivity due to higher softening temperature and lower softening –melting temperature range. Improved quality of hot metal Reduction in coke rate in blast furnaces.
Review of Organic Binders for Iron Ore Agglomeration &#; Iron ore agglomeration is a wet agglomeration process, and moist "green-balls" are subsequently dried and heat hardened at high temperatures to make pellets; the presence of binders affects the entire process from green-ball formation to pellet hardening.
Review of Organic Binders for Iron Ore Agglomeration. Iron ore pellets are one type of ironrich, intermediate product used during primary iron and steel making. During pellet production, finegrained iron containing minerals are liberated from lowgrade ores, concentrated, and agglomerated into round balls that are thermally hardened to form ...
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Recommendations. Sintering is a process of agglomeration of iron ore fines, fluxes, recycled products, slag-forming elements and coke with the purpose of achieving an agglomerated product with the suitable composition, quality and granulometry to be used as burden material in the blast furnace.

Bentonite is an effective, widely used binder in the iron ore pelletizing process. Its low price is an important factor for its extensive use. However, bentonite incorporates silica and alumina, which are undesirable contaminants to pellets. Additionally, it is a natural material with variable composition depending on its origin.
Iron ore can be upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized to be used in the steel making process. Also during the processing of high grade iron ores which don''t need beneficiated, fines which are generated can be pelletized and used instead of being disposed of.

Pellets are balls formed by rolling moist concentrates and fines iron ores of different mineralogical and chemical composition, with the addition of additives and binder, in a horizontal drum or in an inclined ...
The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.
Dec 28, 2015· Iron Ore Agglomeration Processes and their Historical Development. There are four types of agglomerating processes which have been developed (Fig 1). They are (i) briquetting, (ii) nodulizing, (iii) sintering, and (iv) pelletizing.
