The results show that jamesonite and pyrrhotite have good floatability in the pH range of 2-10 and marmatite has good floatability in the acid and it is difficult to separate these minerals. In the pH range of 6-8, the separation of jamesonite and pyrrhotite, marmatite is possible when using mercaptoacetic acid and mercaptoethanol as depressants.
