Synthetic copper ores were made to simulate the ores treated in a copper flotation plant. Chalcopyrite concentration in the synthetic ores was fixed at 4.9 % (corresponding to a 1.7 % copper head grade), while pyrite concentration was made at either 5 or 25 % to represent a low- or high-pyrite feed concentration, respectively. The remaining ...
