    Geochemical investigation of the galvanic effects during

    The main objective of this study was to investigate the influence of coupling sulfide minerals on their respective reaction rates. Five kinetic tests (weathering cells) were set up with three common sulfides. Two sulfide mixtures were prepared and consisted of pyrite and chalcopyrite, and pyrite and sphalerite.
