The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet
Directreduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent.
Although some 45 countries exportnatural iron ore resources, seven countries provide75% of the total exported. The two largest exportersare Brazil and Australia, with about 33% of total worldexports each. Other exporting countries include Chile,India, South Africa, Canada, Russia and the UnitedStates. Iron ore may beshipped in a number of forms:ROM : run of mine, which is ore as it comes from
Energy and Environmental Profile of the U.S. Mining Industry • Agglomerated The development of techniques of mining and concentrating taconite led to the introduction of the ironore pellet. Pellets are comprised of ore that has been agglomerated into balls. The pellet is the major form of introducing iron into the steelmaking blast furnace.

Jan 15, 2019 ·Ł. Introduction. Iron ore pellets are nearly spherical agglomerates of fine iron ore, agglomerating agents and additives that are sintered in a furnace at temperatures of up to 1350 °C in oxidizing atmosphere [].Handling and transportation of these pellets from the pelletizing plant to the reduction furnace of the steelmaker can cause mechanical degradation.
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 ".
Iron ore pelletizing systems. Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel.
