Flotation Process In The Recovery Of Copper From Copper Sulfide

Froth flotation is a process for selectively separating of 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.

Jan 20, 2021· “The single most important method used for the recovery and upgrading of sulfide ores”, that’s how G. J. Jameson described the froth flotation process in 1992. And it’s true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are

The "Gall-Copper Process" was recorded as being used during the Song Dynasty (960-1271AD). Copper was precipitated from solution by dipping iron into the blue vitriol solution - a process identified as early as 150 BC in China. 6 Therefore, presumably, the recognition of a natural copper leaching process can be identified as early as that date.

To be applicable to this process, the ores must contain copper minerals in sulfide form; as mineral such as Chalcocite (Cu 2 S), Chalcopyrite (CuFeS 2) and Covellite (CuS) . In the concentrating operations these minerals are separated from the gangue material of the ore, that might contain as little as 0.5% copper to form a concentrate,

2 Hydrometallurgy is the recovery of metaIs from ores using water-based solutions. As early as 6000 B. C., native copper–the pure metal—was foundas reddish stones in the Med- iterranean area and hammered into utensils, weapons, and tools. Around 5000 B. C., artisans discovered that heat made copper more malle-able.

Feb 04, 2021· Copper sulfate pentahydrate (blue vitriol) is one of the most important industrial compounds of copper [] because of its large number of industrial applications, such as: soil additives, fungicides, and bulk preparation of other copper compounds [].In metallurgy, it is used as an activator reagent in concentration methods by flotation for sulfide ores [], among others [].

This reagent is widely used in the selective flotation of lead–copper–zinc and copper–zinc ores to depress sphalerite, pyrite, and certain copper sulfides. Sphalerite rejection from copper concentrates is often of major concern, as zinc is a penalty element in copper smelting. Cyanide chemistry is comprehensively reviewed by Guo et al,

Sulfide ores are further reduced through a ‘wet grinding’ process that ensures a particle size suitable for the flotation process. Copper leaching. Sulfide ores and froth flotation. Sulfide ores are mixed with water and a surfacant creating a slurry. The slurry, when agitated causes the copper sulfide minerals to float at which point they,

Flotation is a major separation method for metals, coal, and industrial minerals. Most sulfides can be economically recovered by the flotation process. Parameters that influence flotation can be divided into two general categories: (1) the surface characteristics of the minerals and (2) the design of the flotation equipment.
