() Control of grinding conditions in the flotation of

In Fig. 5, 1.5 10 3 mol/l of copper(II), based on the amount of EDTA extracted copper in Table 3, was added during pyrite grinding. It can be seen that addition of copper(II) had exactly the same effect on pyrite flotation as chalcopyrite. Pyrite flotation was improved in the presence of copper(II), especially after grinding with mild steel.
