A method is disclosed for separating phosphate minerals from a mineral mixture particularly from highdolomite containing phosphate ores The method involves conditioning the mineral mixture by contacting in an aqueous in environment with a collector in an amount sufficient for promoting flotation of phosphate minerals The collector is a hydroxamate compound of the formula wherein R is
Oct 15 2020 for the magnesitedolomite flotation system the selective adsorption of hedp onto minerals is closely related to the significant differences in the surface components of dolomite and magnesite the nature of the metal ions exposed to the two minerals is a vital factor that affects the mineral surface activity with the active groups of hedp
