Abstract
In lean coal and lignite, sulfur is predominantly present as organic compounds. According to experiments with a QMC-230 mass spectrometer and an IR absorption analyzer, the removal of sulfur in the reduction of iron-ore concentrates is hindered by the adsorption of sulfur-bearing gases and its absorption by the reduced iron to form FeS, which is not reduced by carbon or hydrogen. Considerable sulfur removal is only observed within a calcium-oxide overburden, by the reaction CaO + H2S = H2O + CaS.
