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 and...
Flotation is the most widely used beneficiation method for fine materials and almost all ores can be separated by flotation Another important application is to reduce ash in fine coal and to remove fine pyrite from coal The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore...
Foam flotation is a process by which collectors condition a mixture of water suspension to make the copper minerals water repellent while leaving the non-Cu minerals hydrophilicFlotation is made from finely ground copper ore in flotation cellsThe previous page explains the types of copper ore that exist and the extraction process that results in finely ground copper or...
Optimization Of Reagent Dosages For Copper Flotation The performance of a flotation unitThe types and quantity of the reagents are the most important part of the flotation processIn commercial plants the control of reagent additions is the most important aspect of the flotation strategy6Reagent schemes used for the treatment of porphyry copper and copper-molybdenum ores are relatively...
The slurry is subjected to a copper flotation process using a collector and frother as required However when copper rimmed pyrite is encountered the process is unsatisfactory due to inefficiency in achieving the desired separation of chalcopyrite from pyrite By way of example a typical traditional process yields a copper concentrate which...

Processes copper mining and production Copper is found in natural ore deposits around the world This page explains copper mining the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living...
The raw ore was characterized by simple composition It consisted of metallic minerals copper pyrite and pyrite and non-metallic minerals quartz and chlorite The multi-element analysis results showed that Cu was the valuable element The Cu grade of the raw ore was 080 Flotation Process...
I read the following In a mixture of \ce PbS \ce ZnS and \ce FeS2 each component is separated from each other in froth floatation process by using the reagents potassium ethyl xanthate \ce KCN \ce NaOH copper sulphate and ac...
The Flotation Process Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical In fact in the last century ores of 4 percent grade were regarded as almost valueless Today such ores which would be regarded as relatively rich in copper are scarce the great majority of mines contain the...
The process choice of copper ore flotation is determined by the raw ore properti Meanwhile there are many determined factors for copper ore flotation process like the mineral disseminated particle size the associated relationship with quartz rock and the gangue mineral typ Only taking full consideration of the factors and using the...
Copper Flotation Process Summary The flowsheet in this study illustrates the modern approach to porphyry copper treatment throughout the industry Each plant will through necessity have somewhat different arrangements or methods for accomplishing the same thing and reliable ore test data are used in most every case to plan the flowsheet and...
Flotation is the conventional method for processing porphyry copper deposits one of the most economically important sources of copper Cu worldwide The rapidly decreasing grade of this type of Cu ore in recent years however presents serious problems with fine particle recovery using conventional flotation circuits...
