Differential flotation of pyrite and arsenopyrite: Effect

15/03/2021 Pyrite and arsenopyrite are the most important mineral phases in sulphide refractory gold ores due to their associative property in hosting gold and concomitant effect on gold extraction processes (Arehart et al., 1993, Asamoah et al., 2018a, Asamoah et al., 2019c, McCarthy et al., 2018, Zhang et al., 2016).

Gold Pyrite, Pyrrhotite and Arsenopyrite Recovery

15/04/2018 In this author’s experience, arsenopyrite/pyrite systems have a tendency to be unique to a given ore body so that what works with one ore does not always work well with other ores. Copper sulfate is often used as an activator in the flotation of gold associated with iron sulfides. Experimentally, when copper sulfate is used in the flotation of gold bearing pyritic ores, the recovery is
