The test aimed at the complete oxidation of the iron to 3. As shown in tion yield tests with iron samples of high Iron 1 Fig.

In these tests, we varied: The carbon content of the iron 0. The combustion time 10, 24 and 36 h. The amount of oxygen available via Cux O. The carbon content was estimated from CO2 - pressure-measurements within our reduction sys- tem [6] and the combusted sample weight.

Initial experiments for the carbon extraction were carried out with Iron 1, 3 and 4 with varying Fig. The standard deviations of carbon content of Iron 4 and Iron 5 are 0.
