Decision system for copper flotation backbone process
Conclusions. This study established a decision system to output a flotation backbone flowchart according to the natural properties of copper ore. The decision system uses XGBoost as a subclassifier to solve small samples and high-dimensional databases. An MCC was proposed to selectively utilize the relations between the sub-labels.

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%.
