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 ...
