2013年7月1日 As expected, the two pyrite ores showed different impact on Cp flotation. The addition of pyrite to chalcopyrite decreased Cp flotation recovery from 96% to 84% with 50% Py-B and to 74% with 50% Py-A after 10 min of flotation (Fig 14 a). This subsequently decreased the Cp grade from 88 to 72 and 66%, respectively.
