One advantage of the iron sintering process is its versatility—the process is quite successful with a wide range of ore fractions (from 0 to 10 mm). Along with clotting, other physical and chemical processes impact iron ore quality. During sintering, up to 90-98% of sulfide and up to 50-60% of sulfate sulfur burn out, and up to 10-20% of ...
