Activation Flotation of Lime-Depressed Pyrite

A series of organic acids, inorganic acids and their salts have been tested as possible activators for the flotation of lime depressed p3oite. The results are presented in Fig. 6.23 and Fig. 6.24. It can be seen from Fig. 6.23 that oxalic acid is the strongest activator in the organic acid series. When the concentration of
