know moreDuring froth flotation the ore is crushed and ground to a specific size sufficient for mineral liberation The ore is then suspended in slurry and mixed with reagent or collectors The collectors react with sulphide mineral particles to make them hydrophobic
know moreFroth flotation also called ore flotation when used in mining applications is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces The particles with attached air bubbles are carried to the surface and removed Froth flotation is one of the most widely used methods for ore beneficiation
know moreFroth flotation of copper zinc lead ores is a complex process based on similar metallurgy processing and strong interactions between chalcopyrite and sphalerite These types of ores represent 15% of the world production and % of copper deposits all over the world
know moreXanthate Application in Copper Froth Flotation In the flotation process of copper ore xanthate mainly reacts with Cu2 Therefore when processing minerals containing more Cu2 on the surface the effect of xanthate is stronger and the order of its action is Cu2S > CuS > Cu5FeS4 > CuFeS2 4 Xanthate Application in Galena Froth Flotation
