Oct ,ironores with lowerironcontent such as taconite are first processed to concentrate theironlevel and drive off volatile impurities theiron oreis dressed or crushed into in chunks, which increases surface area for reactions magnetic separation is used to remove some of the undesirable minerals or gangue in the crushedore
Fines, however, must first be agglomerated, which means reforming them into lumps of suitable size by a process calledsintering. Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together.
Despite the military demand for cast iron, most civil applications required malleable iron, which until then had been made directly in a bloomery. The arrival of blast furnaces, however, opened up an alternative manufacturing route; this involved converting cast iron towrought ironby a process known as fining. Pieces of cast iron were placed on a finery hearth, on which charcoal was being burned with a plentiful …
Theiron-ore finesthat enter the BF need to go through a pelletizing and sinteringprocess. In other cases, such as the smelting reduction (SR) processes that use the fluidized bed technologies theiron-ore finescan directly be charged into the reductionprocessmaking it highly advantageous.
Pelletizingis a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
Oct 23, 2018· Thesintering processis the process of treatment of the fine particles of iron ore obtained from crushing process or in cleaning furnace to collect them in a larger size to be similar and homogeneous particles fit for reduction process.
May 18, 2017· Sintering is a thermalprocess(1300–1400°C) by which a mixtureof iron ore, returnfines, recycled products of theironand steel industry (mill scale, blast furnace dusts, etc.), slag-forming elements, fluxes and coke are agglomerated in a sinter plant with the purposeof manufacturinga sintered product of a suitable chemical composition ...
Jul 10, 2017· thepelletizing processis currently the most widely used option for producing suitable agglomerates for ironmaking applications from fines of iron ore concentrates; quality requirements for DR pellets are higher and since lump ore of the required quality is not available, pellets are the only viable feed for new DR plants;
Iron ore also differs in physical form. Fines requiresintering (agglomeration into crude pellets) prior to use in the blast furnace. Lump ore can bypass this process and be charged directly into the furnace, as canpellets, and bothcommand an associated price premium.
In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning. The mixing step sets the stage for the remainder of the process, creating a homogeneous mixture that will allow for a uniform product to be created. In order to pelletize iron ore fines and/or concentrate, a binder is needed.
Iron oreis converted into various typesof ironthrough several processes. The most commonprocessis the use of a blast furnace to produce pigironwhich is about 92-94%ironand 3-5% carbon with smaller amounts of other elements.

Ironprocessing -Ironprocessing -Iron making: The primary objectiveof iron makingis to releaseironfrom chemical combination with oxygen, and, since the blast furnace is much the most efficientprocess, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percentof ironis made this way.
