1. Estudo eletroquímico das interações entre sulfetos de ferro / Electrochemical study of iron sulphides interactions
The electrochemical behavior of iron sulfides, pyrite, pyrrhotite and arsenopyrite was studied in acetic acid/sodium acetate buffer, pH = 4.5. The investigations included the dissolution of minerals (isolated and mixed in pairs) and the studies of the deposition of silver ions on the electrode surfaces, taking into account the semiconducting properties of ea
