Abstract:A new process of tin hydrometallurgy from stannite concentrate and the electrochemical behaviors of SnS were studied. In the new process, stannite concentrate which was blended with sodium sulphide (NaxS·9H2O)，charcoal powder and sulpher was sintered at the temperature of 650℃ for an hour. Then the processes of leaching, purification and electrolysis were adopted. The mechanism and kinetics of SnS at tin electrode in NaOH-Na2S-Na4SnS4 solution by various kinds of electrochemical methods were also investigated.
Key words: stannite tin hydrometallurgy electrochemistry
