Copper Sulfide Flotation - Mineral Processing & …
Flowsheet for treatment of Copper Sulfide ores rich in minerals such as chalcopyrite with gold and silver as well as arsenopyrite. The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper.
Froth flotation improvement by plasma …
The surface conversion of sulfide mixtures from a sulfide/sulfide to an oxide/sulfide system facilitated separation using the oxide collector Flotinor FS-2. Therefore, the approach of applying selective surface oxidation of mineral mixtures by low-temperature plasma pretreatment seemed to be a promising strategy for improving the separation efficiency of different sulfides by froth flotation.

R. Dunne, in Gold Ore Processing (Second Edition), 2016. 6.2 Depression of Sulfide Minerals With Cyanide. The depressing action of cyanide on pyrite during froth flotation is well known (Sutherland and Wark, 1955) and is widely exploited on many flotation plants to selectively separate copper minerals from pyrite.Depression of pyrite by cyanide during froth flotation appears to take place in ...

Froth flotation is defined as a physico-chemical process which exploits the differences in the electrochemical prope rties of mineral surfaces, that is, between hydrophobic and hydrophilic ...
The Application of Xanthate in Froth Flotation …
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 flotation.Xanthate 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 ...

sulfide minerals, oxides, silicates, etc.) is heavily dependent on processing steps involving control of surface oxidation products on the mineral surfaces and the addition of collector molecules designed to induce a hydrophobic surface for bubble-particle attachment. Separation is then achieved by flotation of the valuable mineral into the froth
1 Froth Flotation – Fundamental Principles
Froth flotation can be adapted to a broad range of mineral separations, as it is possible to use stone treatments to selectively alter mineral surfaces so that they have the necessary properties for the separation. It is currently in use for many diverse applications, with a few examples being: separating sulfide minerals from silica gangue ...

Froth flotation improvement by plasma pretreatment of. We have consequently succeeded in executing a selective surface conversion of a sulfide mineral mixture into oxides during the plasma treatment. This effect had been targeted in order to simplify separation by froth flotation …
Froth Flotation Method - JXSC Machine
Gold flotation. The Froth Flotation Method is means separating minerals according to their different physical and stone properties. According to classification, the flotability of gold and silver minerals is included in the first category of natural and non-ferrous heavy metal sulfides, characterized by low surface wettability and easy flotation, which can be flotation by xanthate collectors.
