The natural pH of the iron ore suspension was about 6.7. So the iron ore particles had very small amount of charge as IEP of iron ore suspension was 5.73 as is evident from Fig. 7. Hence all the surfactants adsorbed to the mineral surfaces in spite of having different charges. SDS and CTAB are ionic with opposite charges as compared to PEG.
