Alcotac – synergistic organic binders

The ores are ground to a fine particle size to separate unwanted impurities and con- centrate the iron oxide. The fine grain of the concentrate is then agglomerated into larger particles to allow further processing in blast furnaces. The most common technology in the iron ore industry to agglomerate concentrate fines is pelletization.

D.R.I. Fines. Direct-reduced iron (DRI), also called sponge iron is produced from the direct reduction of iron ore (in the form of lumps, pellets or fines) to iron by a reducing gas produced from natural gas or coal. Few ores are suitable for direct reduction. Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high temperatures in ...
