sulfidation process during flotation dec

In this paper, sulfidation mechanism of cerussite in the presence of sulphur at high temperatures was investigated based on micro-flotation, X-ray powder diffractometry (XRD), electron probe microanalysis (EPMA) and X-ray photoelectron spectroscopy (XPS). The micro-flotation test results showed that flotation recovery of the treated cerussite increased to above 80% under a suitable flotation condition.
