Froth Flotation of Chalcopyrite/Pyrite Ore: A Critical Review
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%.

Graphite Processing
Normally the flotation process is what is used to separate the graphite from the clay, if this is not happening you may need to adjust your reagents. Alternatively, if the clay is finely disseminated, classification will work after flotation. Do you have the quality specifications - physical (e.g., sizing) and chemical (impurities), etc.?

Froth Flotation Process
Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
