Production of mineral concentrates by froth flotation generates huge amounts of waste – flotation tailings. Approximately 99 % of the ore processed in flotation plants becomes flotation tailings [1,2]. Flotation tailings consist mainly of gangue minerals, mostly quartz, pyrite and silicates with low contents of copper and other valuable metals that were not extracted from the ore by froth ...

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the ...

waste previously ground below 2 mm, using jigging, shaking table and froth flotation techniques. The effect of particle size was also analysed. Jigging and shaking table proved to be effective in the separation of copper from plastics. The result was a copper concentrate with a copper grade of about 97% by both methods and a copper recovery of about 97%. Jigging separation had similar ...

Use of Humic Substances in Froth Flotation Processes

In order to develop a cheaper and greener processes, these hazardous materials should be replaced by more sustainable products, by-products, or wastes generated by other industries. Biosolids, cheaper and greener than chemical frothers and collectors, have been tested successfully in flotation processes. Studies of removal rates and froth flotation kinetics have been carried out independently ...

Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation

17/03/2017  The washed primary slimes are treated by flotation if sufficient recoverable value is present; otherwise, this may go direct to waste. Water overflowing the primary thickener will carry the copper sulphate. This should pass through rectangular concrete tanks filled with scrap iron for copper deposition. The reaction can be speeded up by bubbling compressed air into the scrap iron mass ...

Environmental Impact of Flotation Processing

Environmental Impact of Flotation Processing . Valuable minerals in an ore can be separated from each other, and from worthless minerals, by the froth flotation process. The need for a process to extract ore arose from major sulfide mineralization after the oxide ores had been depleted. The technology involves first crushing the ore, typically to a particle size of about 5 to 50 micrometers ...

60 Centuries of Copper: The Flotation Process

Thus to obtain metallic copper, up to 99 percent of the material mined must be removed as waste. Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and ...

1 Froth Flotation – Fundamental Principles

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay ...
