Etude electrochimique de la pyrite en milieu acide
The electrochemical behaviour of pyrite has been studied in 1 M sulfuric acid. Voltammetric experiments were carried out with synthetic pyrite, using a carbon paste electrode. In this medium, the anodic oxidation of FeS 2 occurs at + 0.98 V vs sce and leads to the formation of Fe 3+, S and H 2SO 4....

| Zusammenfassung: | The electrochemical behaviour of pyrite has been studied in 1 M sulfuric acid. Voltammetric experiments were carried out with synthetic pyrite, using a carbon paste electrode. In this medium, the anodic oxidation of FeS
2 occurs at + 0.98 V
vs sce and leads to the formation of Fe
3+, S and H
2SO
4. The reduction of FeS
2 to Fe
2+ and H
2S occurs at −0.50 V. |
