摘要: Measurements of the rest potential copper sulfide electrodes and pyrite, present in ores concentrates from Lubin Concentrator, have been carried out. Moreover, measurements sulfide-sulfide contact galvanic current were also performed using deoxygenated sulphuric acid solutions as well saturated with oxygen containing Fe(III) ions. Significant interactions observed for couples exhibiting high difference, particularly when sulfides short-circuited pyrite. According to mineralogical data polymineral concentrate, chalcocite bornite are dominating chalcopyrite covellite minor minerals. Expected is advantageous affect pyrite promoting kinetics leaching concentrate a result between sulfides.
