Pyrite cinder samples were ground in a ball mill before analysis to homogenize the samples and reduce grain size. Additionally, spectra were collected from a few samples after grinding by hand in a mortar to ensure that the ball mill grinding did not affect the speciation of the sample. The samples were packed in aluminum frames and sealed with ...

The results showed that adding phosphate and maintaining sufficient oxygen supply during GME treatment in the ball mill passivated pyrite and suppressed its oxidation via the formation of protective iron phosphate coatings. Moreover, the iron phosphate coatings on pyrite made the mineral more hydrophilic, which improved the separation ...
