Innovation in dewatering process of flotation tailings by ...

2016-3-1  Flotation is widely used to clean fine coal particles by separating them from clay, silt, shale and other ash-producing matter using air bubble. After flotation either the coal or tailings slurries must be dewatered for practical and economic advantages.

2018-6-15  The total copper recovered from its ore through flotation process is about 56% [ 6, 18 ], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings sometimes have a higher copper grade (0.2–0.4%) than that of low‒grade ores (0.2‒0.3%).
