Dynamic froth stability of copper flotation

01.08.2018· In this work, dynamic froth stability is used for the first time to investigate the flotation behaviour of copper tailings. Reprocessing of material from tailings dams is not only environmentally desirable, but also increasingly economically feasible as head grades can be high compared to new deposits. Flotation tailings, however, usually contain a large proportion of fine (10–50

New insights into the mechanism of selective

Flotation is commonly used to separate and recover minerals from gangue. Here, flotation was used to separate copper from copper-tin alloy. Vibration mill was used in the fine crushing process of materials. During the flotation process, the froth product is copper, and the material sinking to the bottom of the flotation cell is solder.

Water-soluble frothers, (Dowfroth 250 and Cyanamid AF65) are often stage-added along a flotation bank to maintain a stable froth phase and reduce consumption. Flotation operators must pay close attention to froth characteristics as changes in the appearance are indicative of ore or circuit changes.
