· Pure mineral flotation results have shown that MSO is more tolerant to fluctuations in pH, pulp temperature, and reagent dosages than SO. Adsorption tests, zeta potential measurements, and solution chemistry analysis have revealed that MSO has a greater collecting ability to quartz than SO because of the double collecting groups of MSO.
