The oxidation of pyrite under acidic conditions, an important process leading to the formation of acid mine drainage, has been the subject of intense research yet remains incompletely understood. In this study, the mechanism of the electrochemical oxidation of pyrite in a pH 2 electrolyte was investigated using electrochemical techniques. The morphological changes and oxidation products of pyrite...
The efficiency of polysiloxane coating to suppress the pyrite oxidation under environmentally relevant conditions was investigated with electrochemical techniques. Cyclic voltammogram, Nyquist plot or Tafel test were preformed in the conditions of different polysiloxane proportions in modifying agent, pH values, Fe 3+ concentrations and volumes of water impact. The increased proportion of...
