Hematite (Fe2O3) → Pentacarbonyliron(0)

Participants

Reaction Steps

"C" grade carbonyl iron powder, 6-8 micron size from GAF was mixed with iron ore concentrate and the blend was then agglomerated by briquietting at 51,000 psi into briquettes 12.5 mm×12.5 mm diameter. The briquettes were indurated by heating from room temperature to 600° C. in 25 minutes, held by 600° C. for 20 minutes and then air quenched to room temperature. The compressive strength of the briquettes was then determined. Table I below sets forth the results obtained with different levels of iron carbonyl added, with three different types of iron ore concentrates.
