THE USE OF PULP POTENTIAL CONTROL TO SEPARATE

If the flotation behavior of tennantite were similar to that of enargite, the most likely pulp potential region for making a separation between copper-iron sulfides (such as chalcopyrite and bornite) and tennantite is at reducing conditions as illustrated in Figure 1. While the data in Figure 1 was obtained at pH 8, the dependence of enargite
