This study explores the flotation behavior of chalcopyrite in the presence of different concentrations of sodium sulfide (Na2S·9H2O) at pH 12 under controlled potential conditions. It was observed that the flotation of chalcopyrite is not depressed completely when the pulp potential is low, even at high concentrations of sodium sulfide, i.e., 10−1-10−2 mol/L.

ranges 1.5 - 3 % Copper grade and 0.2- 1 % Cobalt grade[1,2]. The principal used method of concentration is sulfurizing flotation, producing final concentrate with grades of 10- 16 % Copper and 0.6 - 1.2 % Cobalt,and yields of 50- 70 and 30 - 60 %, respectively. However, tailings contain a considerable amount of valuable metals.

With a different volume, a different amount of water would have been displaced, thus a different mass. . With a different mass the buoyant force would be different on the crown and the gold weight, thus they would be tipped out of balance. We tested this same principle during our lab. We started by attaching a force sensor above a beaker of water.
