Resumen
ALMEIDA, C.M.V.B. y GIANNETTI, B.F.. Acid Production from Mixed Sulfide Minerals: The Mixture Pyrite/Arsenopyrite. Port. Electrochim. Acta [online]. 2003, vol.21, n.3, pp.201-212. ISSN 0872-1904.
To evaluate the response of pyrite and arsenopyrite to oxidizing conditions, an electrochemical approach was employed, to set boundaries for the influence of the arsenopyrite content. The effects of galvanic interactions and local pH on the oxidation reaction of pyrite were also studied. With this purpose, artificial two-mineral electrodes were constructed ranging in concentration from 20-80 % arsenopyrite. The resulting cyclic voltammograms were analyzed and relative quantities of oxidation products were evaluated.
