  • CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

    FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in productivity and saving in coke Pelletization is the third major step in taconite ore processing. Iron ore concentrates must be coarser than about No. 10 mesh to be acceptable as blast furnace feed without further treatment. Finer concentrates are agglomerated into small "green" pellets, which are classified as either acid pellets or flux pellets. Acid pellets are produced from iron ore and a binder only, and flux 11.23 Taconite Ore ProcessingDifferent percentages of iron content reflect both the natural variation in iron ore grades found in mine deposits and the degree of processing (if any) employed to upgrade the ore for a certain use. In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke required. For these reasons, the rule of Iron ore pricing explained Metal Bulletin
