•Sulphidisation of oxidized pyrite at −200 mV (SHE) reduced the amount of ferric-hydroxide and generated elemental sulphur.•Sulphidisation of oxidized pyrite at −200 mV (SHE) could not convert the oxidised surface into an iron sulphide form.•Iron sulphide species were only formed on oxidised pyrite...
