In practical celestite flotation, iron contamination is commonly found on celestite surfaces. The effect of ferric ions on celestite flotation was assessed by a combination of ion release experiments, DFT calculation, Xray photoelectron spectroscopy (XPS) analysis, adsorption isotherm study, and flotation experiments in this work.
