1.1 Basic concept of flotation process Flotation process, where the separation of minerals from complex ores is based on the difference in their hydrophobic features, is performed at the contact of three phases: solid–liquid–gaseous. In this three-phase system (usually, this system consists of ...
(redirected fromFroth-flotation process) Encyclopedia 1.A process of separating the substances contained in pulverized ore or the like by depositing the mixture on the surface of a flowing liquid, the substances that are quickly wet readily overcoming the surface tension of the liquid and sinking,...
In the concentration of metallic and non-metallic minerals by froth flotation with a high content of pyrite and the like iron sulfides, which includes the subjecting of such ores when finely ground and sized to substantially liberate particles of pyrite, to froth flotation process in the presence...
