Iron is extracted from iron ore and it can be found in a variety of forms including cast iron wrought iron and pig iron Difference Between Carbon Steel and Iron The main difference between carbon steel and iron is that carbon steel contains a small amount of carbon whereas iron does not contain any carbon Carbon steel is stronger and
Iron ore lumps size 10 40mm Iron ore fines Granular size of up to 10 mm for up to 90% of the cargo While lumps are crushed to 5 20mm size in crusher normally 30% fines waste will be generated
DRI also known as sponge iron is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron below the melting point of iron and typically in the range of 800 1200 °C Iron oxide is charged into shaft furnace rotary kiln or fluidized beds in the form of pellet iron ore lumps or fines The reduction takes place using gaseous reductants CO H
Iron usually appears dark brown from oxidation or impurity but when pure or on a fresh surface is a gray or white metal It is easily oxidized rusted by moisture and is attacked by many corrosive agents Symbol Fe Latin Ferrum Atomic number 26 atomic weight Specific gravity pure iron ; cast iron
Sponge iron produced in India is mainly for domestic consumption but a limited tonnage is exported to nearby markets What are the main differences between the various types of OBMs Pig iron is produced mainly by smelting iron ore in a blast furnace and then casting the hot metal liquid iron into ingots ingot weight ranging from as

Cost and supply of iron ore coal and natural gas are some of the raw materials that affect the production cost and in turn affect the price of sponge iron What is the difference between sponge iron and normal iron Is sponge iron flammable; Facebook Twitter Youtube Instagram Linkedin today scrap rate
High grade iron ore less than 10% of the total reserves ROM iron ore with Fe less than 58 60% discarded as waste After beneficiation iron ore availability can improve by about 50% Steel community and the country demand technological solutions for utilising low grade ores The technology task that would be imperative 1
Characteristics of Iron Ore Concentrate and Fines Iron Ore Concentrate Iron ore concentrate is a processed product derived from iron ore It is composed primarily of iron oxides and contains a high percentage of iron typically between 63% and 70% The key characteristics of iron ore concentrate are 1
The iron ore production has significantly expanded in recent years owing to increasing steel demands in developing countries However the content of iron in ore deposits has deteriorated and low grade iron ore has been processed The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking This chapter
Composite briquettes or pellets consisting of iron ore carbon and a binder are a source of direct reduced iron DRI In the handling of green and reduced briquettes high strength is important to minimize briquette breakdown The use of charcoal as a source of carbon rather than coal provides a way of introducing renewable carbon into the ironmaking process
The employed fuels are natural gas and/or coal The energy consumption is in the order of GJ/t DRI that is equivalent to 300 m 3 of natural gas per ton of reduced iron The CO 2 emissions are quantified in the range t of CO 2 per ton of steel As a function of the employed reducing reactors the systems are of four main types
These processes operate with different feedstocks The BF BOF pathway converts raw iron ore to pig iron and then to steel HM whereas EAF converts both steel scrap and sponge iron to steel HM DRI converts raw iron ore to sponge iron a porous permeable and highly reactive product that requires treatment with EAF before selling to market
Download scientific diagram Comparison between pellet and DRI Sponge iron in SDI size distribution index from publication Influence Of Iron Ore Pellet Size On Some Properties Of Sponge
DRI converts raw iron ore to sponge iron a porous permeable and highly reactive product that requires treatment with EAF before selling to market One of the well known hard to abate sectors substantial iron and steel industry decarbonization will increase production cost significantly >120 $/ton [ ETC 2018 ] The difference of
What is sponge iron Sponge iron also known as DRI direct reduced iron or direct reduction iron bulk density /cm3 apparent density /cm3 typical size 4 20mm is a kind of material produced by the reduction of iron ore with reducing gases such as H2 or CO gas generated from various carbon or hydrocarbon resources The name is got because
pyrite ash waste The feasibility use of low grade iron ore with microwave roasted pyrite and pyrite ash in production sponge iron were tested and the physical chemical properties of the products regarding the results of microwave roasting tests were determined by examining the difference between the
In India there are many small rotary kiln furnaces producing DRI known locally as sponge iron using coal as energy and reductant source Some of the sponge iron plants are captive to steel mills but there is a significant domestic merchant market India producing 57% of its crude steel in electric arc furnaces 2016
Sponge iron produced in India is mainly for domestic consumption but a limited tonnage is exported to nearby markets What are the main differences between the various types of OBMs Pig iron is produced mainly by smelting iron ore in a blast furnace and then casting the hot metal liquid iron into ingots ingot weight ranging from as
4 Erztransportband=ore conveyor belt; Eisenschwamm=sponge iron DRI ; Transportband=conveyor belt A successful gas based direct reduction process is the Midrex shaft furnace process developed by Midland Ross Corp of Toledo Ohio in 1967 [10] Figure 3 The main facilities of a Midrex direct reduction

Sponge iron is produced through direct reduction of iron ore in the solid state Sponge iron is an iron source relatively uniform in composition and virtually free from tramp elements It is mainly used in Electric Arc and Induction furnaces to dilute the contaminants present in the scrap It has an associated energy value in the form of
The quality of pellets is often dependent on amongst other factors the quality of the iron ore Why Is There a Rising Demand for Iron Ore Pellets The demand for Iron Ore Pellets has been steadily rising in the last decade The reasons for this are 1 Iron ore reserves have been steadily declining After all iron ore is a finite natural
