Flotation of Pyrite - 911metallurgist

2017-5-3  Sodium silicate was somewhat effective in causing a differential or selective flotation of copper, as chalcopyrite from pyrite by keeping pyrite from floating. Sodium hydroxide and sodium sulfide gave, in most cases, a distinct separation of sphalerite from chalcopyrite; i.e., a high copper and low zinc by suppressing the flotation of sphalerite.

2017-3-25  The presence and abundance of these species on the surface depends strongly on the electrochemical conditions [4]. The most important step in the pyrite oxidation process is the breaking of strong bond between sulfur and iron atoms, and formation of thiosulfate ion as intermediate product (Reaction (5)) [51].

2021-3-10  C. Flotation Procedure After the required size fraction of 75μm and below was obtained by screening after milling, 1kg (per batch) of ore was put into the flotation cell and mixed with 2L tap water by means of an agitator which was slowly immersed into the cell. The agitator was started after closing the valve and agitation was performed for 5 minutes. The initial pH of the solution was measured with a calibrated pH meter prior to addition of any reagents. The initial pH was found to be around 7.8 and 0.05g of CaO (lime) was added to adjust the pH to the desired value (8.5). Then solution was conditioned for 5 minutes. Thereafter, other reagents: activator (CuSO4), collector (NMBT) and lastly frother (Senfroth XP 200) were each added at intervals of 5 minutes conditioning time. Flotation was started by opening air valve. The froth was then collected using a plastic scraper, into the concentrate pans for a period of 15 minutes until all the concentrate was collected. Once the flotation
