There are more than 20 types of mineral flotation.Universal separation method, because by using flotation can be separated almost all minerals.It is used for all types of ores and minerals chalcopyrite, molybdenite, galena, sphalerite, gold, talc, mica, carbon, rare earth mineral, uranium minerals, and others.
The flotation reagent consumptions are minimum.The majority of chalcopyrite remains in the sulfur flotation tailings and can be readily recovered by flotation with different flotation reagents.When amyl xanthate is used, 85 of chalcopyrite can be recovered with a copper grade of 14.5 in a single-stage froth flotation.The chalcopyrite.
In this paper the particle interactions between sphalerite and silica were studied by zeta potential measurements and a novel zeta potential distribution measurement zpd method in different concentrations of calcium ion solution.The flotation reagent adsorbed on the mineral surface was analyzed by the interaction behavior.
