Study of Temperature Profile in the Induration of Magnetite Iron
The deficit of high grade iron ore has opened up the thrust of research towards utilisation of low grade iron ore fines/slimes/lean grade ores in combination with beneficiation and pelletisation processes [1,2,3,4]. Pelletisation of ultrafine iron ore concentrate can promote conservation of iron ores by the utilization of lean grade slimes to the tune of 10 to 15 % of run-off-mine (ROM). Low grade fines and slime occupy huge space and cause environmental and ecological problems. Adoption of a combination of techniques for mining, beneficiation, sintering and pelletisation of ore has resulted in increased use of the fines in iron making.

Effect of limestone and dolomite flux on the quality of pellets
Owing to the depletion of high-grade iron ore quality, many steel plants over the world are now using pellets after beneficiation of low grade ores as blast furnace feed. For the effective utilization of low-grade iron ore resources (59–62% Fe) with high loss of ignition (LOI), mineralogical characteristics play the vital role to improve the process International PranaGraf Mintech Research Centre.

Strengthening pelletization of manganese ore fines containing
Pelletization is one of useful processes for the agglomeration of iron ore or concentrates. However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets. In this work, high pressure roll grinding (HPRG) process and optimization of temperature For the effective utilization of low-grade iron ore resources (59–62% Fe) with high loss of Heating cycle of iron ore pellets is one of the prime segments of the whole pelletisation process.Pelletization of hematite and synthesized magnetite concentrate
