Chalcopyrite and pyrite show recovery of over 90% when working with SBX and MIBC at pH 4–10. An increase in pH to 11.5 allowed lowering the pyrite recovery to 63%. However, when using PCA, pyrite flotation was significantly reduced at pH 4–8, while chalcopyrite was slightly affected, with recoveries over 90%.
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay in the liquid phase.

After being rinsed, if the sample contains feldspar and mica it will be frothed. To efficiently separate feldspar and mica from quartz, we have developed a procedure that makes feldspar and mica ...
A part of hydrometallurgical and pyrometallurgical technologies mentioned above, froth flotation arises as an attractive, low-cost and suitable technology for separating the battery materials due to the high inherent hydrophobicity of graphite and the significant density difference between graphite and the cathode materials [12].
Then, the graphites and cathode materials were recovered by froth flotation. Reportedly, with a rougher flotation stage, the underflow product obtained had a grade of 94.7% with respect to cathode materials with a recovery of only 83.7%. However, this method greatly increased the cost due to the implementation of pyrolysis under an …
