·Agglomeration processes are necessary to utilize the iron ore fines 10 mm that are generated due to mechanized mining of iron ore Sintering is one of the most prevalent agglomeration processes due to its lower capital cost and operational flexibility Sintering combines iron ore fines in the size range 10 mm along with fluxes
The iron ore fines − 10 mm are agglomerated using Dwight Lloyed sintering machine The iron ore fines and coke breeze fines mix with moisture is fed on the sinter bed which is ignited by a gas burner to initiate sintering process The hot sintered ore is discharged at the end of the machine
·The sintering process can be defined as a thermal agglomeration process that is applied to a mixture of iron ore fines recycled ironmaking products fluxes slag forming agents and solid fuel coke with the objective of obtaining a product with the suitable characteristics thermal mechanical physical and chemical to be fed to the blast furnace
·What are iron ore pellets Iron ore pellets are spheres of typically 8 16 mm to be used as feedstock for blast furnaces They contain 64 72% iron and additional materials which can adjust the chemical composition and metallurgical properties of the pellets The iron ore pelletization is the process of converting iron fines less than 200 mesh

The schematic represents the HBI briquetting process Direct Reduced Iron is discharged hot from the reduction furnace and screw fed into the nip between two counter rotating rollers Pockets in the synchronously rotating rollers form the briquettes Briquetting machine for DRI from pellets and lump ore roller diameter 1 000mm Figure 4
·Iron ore sinter plants are energy intensive components of integrated iron and steel production see Table 1 where the iron ore fines <5 mm are converted into larger >5 mm lump sinter cakes with greater gas permeability which are the most important burden materials for iron making in blast furnaces BFs [7] The main process is shown in Fig 2 and described in
·To know more about this process and iron ore mining contact us and learn all about iron ore polyurethane  and the associated processes of processing iron ore Stockpiling And Crushing Before being crushed the iron ore must first be broken up to an F 80 grind size
·The mineral processing of iron ore generates a large quantity of fines considering particles under 5 mm in size [1 2] Blast furnace BF ironmaking involves a vertical counter current process
·Theoretically the highest iron content in iron ore is around 72% and iron ore with an iron content above 60% is called rich iron ore Iron ore is first reduced to iron pig iron in a furnace then sent to a steel making furnace for decarburization and refined into steel Scrap steel can also be melted and regenerated in a steel making furnace
Sintering Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together For this purpose a traveling grate machine is used and the burning of fine coke known as coke breeze within the ore generates the necessary being delivered to the sinter machine the ore mixture is moistened to cause fine particles to
·This process of converting iron ore into pellets is known as Pelletization Iron Ore Pellets are then used in the production of steel Pellets are usually preferred instead of raw Iron Ore because it allows for maximum utilization of iron ore This concentrate is then passed through a specialized machine known as a disc pelletizer that
·used to recycle iron containing waste such as steel slag and dust sludge from the production process of steel mills which reduces costs and protects the environment Cur rently there are two methods of lumping pelletising and sintering of which sintering is the main method [35 36] The flow of the iron ore powder sintering process is
·GRAVITY CONCENTRATION OF IRON ORE R K Rath and R Singh INTRODUCTION Gravity concentration process is the oldest beneficiation method known to mankind concentration of tin beach sand iron ore tailings and gold More recently a purpose built machine for iron ore industry was first tested at IOC Canada in 1998 and IOC is
