What is the difference between pellet and sinter? – Wiki REF
Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals.. Sinter and pellets are agglomerated forms of iron ore, both suitable for use as blast furnace burden …
