Ethyl isobutyl xanthogenic acetate (EIBXAC) was used as a novel collector in the flotation of secondary copper sulfide minerals owing to its ability to separate copper and sulfur. The collectivity and selectivity mechanisms of this novel collector were investigated using single-mineral and artificial mixed-mineral tests, combined with …
The flotation separation of Cu-Fe sulfide minerals at low alkalinity can be achieved using selective depressants. In the flotation system of Cu-Fe sulfide minerals, depressants usually preferentially interact with the pyrite surface to render the mineral surface hydrophilic and hinder the adsorption of the collector. This review summarizes …

Slime table mineral processing is a method of separating mineral particles on an inclined bed surface, it can allow the minerals to be loosened, layered, and zoned through the combined action of the asymmetric reciprocal motion on the bed surface and the water flows on the thin layer sloping surface, thus achieving the separation of minerals ...
Figure 11.1: Principle of dense medium separation. Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the rejection of gangue prior to grinding for final liberation. It is also used in coal preparation to produce a commercially graded end …

High Gradient Magnetic Separation of small (5-38 µm) weakly magnetic copper mineral particles from a copper concentrate and ore has been performed.
Introduction. The selective separation of copper–molybdenum sulfide minerals by flotation mostly relies on the use of various depressants. Sodium hydrosulfide, sodium sulfide, cyanide and Noke's reagent (thiophosphorus or thioarsenic compounds) are routinely used as the selective depressants of chalcopyrite (Bulatovic, 2007, Pearse, …

High Gradient Magnetic Separation of small (5-38 µm) weakly magnetic copper mineral particles from a copper concentrate and ore has been performed.
Gravity separation has been used for centuries to separate different minerals and metals based on their specific gravity. Some of the earliest recordings of this science in practice are from Ancient Egypt as workers panned for gold in the Nile river.
The separation and enrichment of copper and zinc minerals from the raw ore by flotation mainly depend on the reagent regime and the flotation process. The Z …
This work mainly reviews and combs the physical separation methods, chemical separation methods and combined separation methods used to separate …
Mineral processing - Concentration, Separation, Flotation: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour …
This ability to modify the floatability of minerals has made possible many otherwise difficult separations that are now common practice in modern mills. Flotation is widely used to …

This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) …
Gravity separation of minerals is based upon the difference in specific gravity between the target mineral and gangue minerals (Wills and Finch, 2015). The most often used equipment in the gravitational separators include jigs (Falconer, 2003), spirals (Falconer, 2003; Sadeghi et al., 2014), falcon (Gülsoy and Gülcan, 2019), …
The separation of copper and nickel is achieved by differential flotation, if the mineral grains can be liberated by grinding. Normal practice is to depress the nickel sulfides by increasing the pH of the flotation pulp to between 9 and 11 and selectively floating the copper minerals.
For copper oxide ores that contain weak magnetic copper-bearing minerals, such as libethenite, and copper-bearing limonite, after sulfidization flotation, the flotation tailings can be reseparated by high-gradient magnetic separation.
The findings of synchrotron based spectromicroscopic investigations of Cu and xanthate adsorption onto pyrite surfaces are reported. Synchrotron based photoemission electron microscopy measurements have revealed that Cu adsorbs only onto specific surface sites on pyrite. The Cu 2p X-ray absorption near edge structure and position …
And it is a type of hydroxy copper carbonate, which is formed by oxidation and chemical precipitation of primary copper sulfide mineral [3]. As we all know, froth flotation is considered to be an effective method for enrichment and separation of copper oxide due to its simple process, cost effectiveness and environmental friendliness [4] .
