Abstract
Study was carried out on extraction of sulphides in iron and steel and separative analysis of FeS and MnS in the extracted residues. For extraction of sulphides, the electrolytic method with constant potential and neutral electrolytic solution (5% sodium citrate, 1% potassium bromide, 1% potassium iodine) and at low temperature below 5°C was found to be most favourable. For the separative analysis of FeS and MnS in the extracted residues, the hydrogen reduction method was most favourable. FeS in the residue was reduced completely in about 2 hr in the stream of hydrogen at 800-900°C and the corresponding H2S was generated, on the other hand, MnS remained without change, even if the residue was a solid solution of FeS-MnS.Keywords
