| Resumo: | Cold agglomerated iron ore mini-pellets (diameter 3–8 mm) with high mechanical strength were prepared. The use of carbon-based nanomaterials (carbon nanotubes and graphite nanoplatelets) as additives to the binder (liquid sodium silicate) promoted the increase of the mechanical strength of the agglomerate to about 285%. The dispersion of the nanomaterials into the binder combined with the resting time of the dispersed material were considered key points on the formation of agglomerates with high mechanical strength. The results have shown that the solely use of ultrasonic processor is inefficient to disperse the nanomaterials into the binder. However, using a resting period of approximately fifteen days, the dispersion of the nanomaterials has improved considerably. Subsequently, the increase in the mechanical strength of the agglomerate (mini-pellet) was related to the dispersion capacity of the nanomaterials in the sodium silicate. |
