  • Flotation | ore dressing | Britannica

    Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water The flotation process was developed on a commercial scale early in the 20th century to01/11/2011· Mineral species such as talc, carbon and carbon associated minerals, such as carbonaceous pyrite, can all be difficult to depress in a flotation circuit OnMineral Flotation Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out This method of froth floatation is a method of mineral processing in which different minerals are separated selectively Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatationFroth Flotation Process Detailed Explanation With

  • The Application of Xanthate in Froth Flotation Process

    Xanthate, as the flotation collector with strong collection effect, is mainly used to enhance the hydrophobicity of the mineral surface to meet the requirements of flotationXanthate is commonly used in the flotation process of sulfide minerals Xanthate is a combination of alcohol, sodium hydroxide and carbon dioxide, which is an anionic collector It is light yellow, soluble in water andThe flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore At present nearly 2 billion tons of ore in the world are treated by the froth flotation process According to rough statistics, about 90% of nonferrous minerals are recovered by the flotation method, accounting for 50% proportion in the field of ferrous metalFlotation Machines | Mineral Processing MachineSynopsis This paper presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure, surface chemistry and electrochemical characteristicsPrinciples and practice of sulphide mineral flotation
