In the flotation of carbonate-hosted Pb-Zn ore, the separation of dolomite is critical to obtain high-quality zinc concentrate. In this study, fine-grained dolomite was found to be more floatable than coarse-grained dolomite, and it was the main cause of magnesium contamination. Entrainment dominated the flotation of fine-grained dolomite.Web
