Grate-Kiln System for iron ore pelletizing
The plant took iron ore concentrate and produced superior iron ore pellets (which are spheres of high iron content and uniform quality) for blast furnace and direct reduced iron feed. Since then, Grate-Kiln systems have been used for over 50 plants, on both magnetite and hematite ores, with an installed capacity of over 115 million tpy.

The Midrex and Energiron gas-based processes use predominantly iron ore pellets as feedstock, but sometimes with inclusion of lump ore in the furnace charge. The Finmet / Finored gas-based process utilizes iron ore fines as feedstock. The SLRN coal-based rotary kiln process uses lump ore and, increasingly, pellets as feedstock.
