• Leaching of chalcopyrite with ferric ion. Part I: General aspects (2008, background): “To account for these results, they proposed a reaction model involving incomplete reduction of chalcopyrite, according to the following reaction: CuFeS2 þ 3Cu2þ þ 3Fe2þ→2Cu2S þ 4Fe3þ ð7Þ This reaction is followed by oxidation of Cu2S (more sensitive to leaching than chalcopyrite) by ferric ion: Cu2S”
• The evolution of surface layers formed during chalcopyrite leaching (2006, background): “The decrease in Fe concentration at the surface after 2 h of leaching (Table 3) is due to the removal of Fe(III)–O–OH and the exposure of the Fe-depleted under layer (Mikhlin et al., 2004).”
