Maximizing the Recycling of Iron Ore Pellets Fines Using …
By preparing the fine ores by the method of pelletization or briquetting, gaseous emissions are lowered, in comparison with the sintering route. Pelletization process is preferred for the agglomeration of very fine particles, of micron ranges . Hence, briquetting will be the best type of agglomeration for coarser particles [5,9].

Characterization of Iron-Bearing Dust Pellet in Composite Agglomeration …
Composite agglomeration process (CAP) is an effective method to utilize the iron-bearing dusts generated in the ironmaking plants, by which the dust percentage in the sinter feed can be increased up to 20 wt %. In the current study, a comparison on behavior of iron-bearing dust in the conventional sintering process (CSP) and CAP was characterized.
