It is relatively unselective. It has a strong tendency to float iron sulfides unless depressants are used. • Potassium amyl xanthate (PAX) is used as a good mining reagent for the flotation treatment of all sulfide minerals, Cu/Ni sulphide ore, zinc ores, as well as gold associated with pyrite( gold containing iron sulfides).
