CONCLUSIONS Sodium sulphide is an activator in the flotation of willemite and hemimorphite with amines. Due to chemical and structural differences between the two minerals, its effect on willemite is stronger than on hemimorphite. The sodium hydrosulphide ion, HS'', is the predominant species in the pH range of sulphidization and flotation (10
