The runofmine ore processing consists of crushing and wet screening to reduce the ore to 6 mm size. Gravity separation methods, employing jigs, spirals and hydroclassifiers, are utilized to upgrade coarse fractions. Materials below mm are separated by wet high intensity magnetic separators ("WHIMS").

Jun 14, 2019· Steelmakers would ideally prefer high grade iron ore lumps, but its availability is limited. The immovable stocks at mines are also on account of many beneficiation plants being idled – a total capacity of 47 mt in Odisha alone and pellet capacity being currently underutilised, PMAI countered. Half of the mt of iron ore fines stockpiled in Odisha is above 60 Fe grade ore that can be beneficiated .

Some iron ore companies are already marketing 'green' iron ore pellets, while others are only just starting to develop beneficiation processes for their production sites. For a highgrade iron ore deposit (ie greater than 62 per cent), a dry crushing and sizing process is sufficient to achieve the required product quality and size fraction as lump ore, sponge ore or sinter fines (MetalBulletin, 2014).

Energy and Environmental Profile of the 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.
