Main drivers influencing development: Ore
• Mineralogy is changing (easily mined ores exhausted)
Reductants• Availability vs cost
Power• Limitations imposed• Cost
Environmental• Effluent• Water usage

Reduces power consumption by pre-heating feed
materials
Can be retrofitted to some existing furnaces
Reduces furnace building height and subsequent
overall plant footprint
Effectively utilise energy contained in furnace off-
gas
Best suited to furnaces with
agglomerated feed
