Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.
EUROFER REACH position on Iron Ore Pellets and Sinter If the iron ore fines are Fe2O3 and processed into pellets, then theoretically, no chemical change will occur as Fe2O3 is still there at the end point of the pellet EUROFER REACH position on Iron Ore Pellets and Sinter. 28 October 2008
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.
Marcus Hanna, the national Republican political figure, then married into the Rhodes family setting the stage for a change. It became Hanna Mining in 1885. In the mid-1860s the company expanded into iron ore mining in the area around Lake Superior. Incorporation took place in 1922 and was named as the M.A. Hanna Company.
Iron ore pellets are piled up at the steel plant of the steel producing company ArcelorMittal in Hamburg, Germany, 14 September 2012. The largest steel producing company in the world ArcelorMittal expects a decline in the demand for steel in Europe by three to five per cent.
Chemistry ch. 2. STUDY. PLAY. Iron ore is heterogenous mixture that contains iron oxide. Iron ore can be smelted to produce pure iron. Is ieon smelting a chemical or physical process? Chemical because you took a compound and broke it down to an element. Air -- oxygen + nitrogen.
iron ore, water and a binder are balled in a mechanical disc or drum to produce wet pellets. Bentonite is the most widely used binder in iron ore pelletizing industry. The use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet properties, however, because of its acid constituents (SiO 2
concentrate or even pellet feed has been added to the sinter mix. The increased usage of these types of ores have resulted in larger focus on agglomeration, either by the use of intensive mixers, but also usage of various binders . The LKAB production volume is dominated by iron ore pellet, however a significant volume
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
Six additives, i.e., limestone, lime, magnesite, magnesia, dolomite and light-burned-dolomite, were added for investigating their influences on the pellet quality. For green balls, adding lime and Influence of flux additives on iron ore oxidized pellets | SpringerLink

1-4-2000To get to the bits of iron in the ore, you have to smelt it out. Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores.

change, but also significantly reduce production costs, because you need carbon to produce liquid iron, which is produced in a chemical process. The carbon atoms bind the oxygen atoms present in iron ore (which is basically iron oxide), to produce pure liquid (lumps of iron ore) and pellets (small balls of iron ore) and cokes.
