Why Pellets? Pellets are made of Iron Ore fines which once were disposed of as waste. These fines are now rolled into ball small balls, and then fired in a kiln to sinter the particles into a hard sphere. Pellets are formed from beneficiated iron ore fines. Pellets are reduced faster than sinter and iron ore lumps.
