Sintering : In sintering fine mineral particles are agglomerated into a porous mass by incipient fusion caused by the heat produced by combustion within the mass itself. In this case the iron ore fines and other iron bearing recycling materials are mixed with fluxing material, moisture and solid fuel normally coke breeze and fed to the permeable grate of sintering machine.
