In the differential flotation of copper and iron sulphide ores, one of the most trouble-some points is how to reactivate the iron sulphide minerals after the flotation of copper minerals, in which iron sulphides are depressed by quicklime. In such a case, it is well known that if the acidity of the pulp is very high, iron sulphides may be easily floated, but it is very inconvenient and impractical to subject them to strong acid treatment in actual operation. Accordingly, studies on the activators of iron sulphide minerals in alkaline condition were carried out to appreciate the efficiency of ammonium salts. Pyrite from the Hitachi Mine, Ibaragi Prefecture, and pyrrhotite from the Akagane Mine, Iwate Prefecture, were used as samples and ammonium salts such as NH_4NO_3, (NH_4)_2SO_4, NH_4Cl, NH_4F and (NH_4)_2CO_3 as activators. Figures 4-10 and Tables 4-5 show the results of these studies. Some data obtained in the milling plants of the Akagane, Miyatamata and Takahi Mines are cited as examples of practical application of the method of research followed by us.
