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 ...
After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation …
The froth of copper-rich bubbles at the top of the tank is then skimmed off for further processing. The gangue sinks to the bottom of the tank to be removed or disposed of as mine tailings. The next stage after froth flotation is the thickening stage. The froth is poured into large tanks called thickeners.
To start with I will give you a simplified description of how selective froth flotation works, lets start over again with a description of the equipment and why it works. When the grinding circuit is finished with the ore it will be ground very fine and the density of the slurry will be between 30% to 45% solids. This is very important because the slurry will be treated chemically and air will ...
Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide (usually chalcocite), which can then be activated by the froth flotation plant.

Copper Sulfide Flotation. Coal is somewhat unique in that it constitutes the major component of the pulp and is the floated species. The possibility exists that the froth generated in coal flotation coincidentally agrees with the mechanical model. Copper sulfide ore, being more dense and with floatable valuable material of about 1% or less, is ...

Copper processing is a complicated process that begins with mining of the ore (less and purify copper from copper sulfide ores, in four basic steps 1) froth flotation, The copper concentrate is first sent through the smelting furnace to be
In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.
Jan 15, 2019· 1. Introduction. Chalcopyrite, the major mineral for copper production, is often found finely interlocked with iron sulfide minerals, particularly pyrite (Owusu et al., 2014).Pyrite is usually perceived as a gangue mineral and removed by flotation to minimize its contamination in copper concentrates (Wang and Forssberg, 1991).In froth flotation, hydrophobic particles are supposed to attach to ...
Our range of flotation solutions include frother and collector programs for coal, copper, molybdenum, phosphate, potash, and more. All of our solutions address your process holistically, helping you optimize your flotation circuit to achieve greater selectivity, recovery, grade, and ultimately, cost performance.
The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching. The ore with 4.21% copper grade used in this study was obtained from Çorum-Dangaz region of Turkey. Native copper, cuprite (Cu 2 …
Aug 01, 2018· A laboratory scale, unstirred flotation column was used for the dynamic froth stability experiments in a modified Bikerman test.This set up is similar to the systems used in a variety of other studies (Ip et al., 1999, Cilek and Karaca, 2015, Li et al., 2017).The column was 157 cm tall with graduations on the front wall and a square cross sectional area of 139.2 cm 2.

However, after activation of the copper salt activator, the surface of the sphalerite is easily adsorbed by copper ions and becomes floatable, and the low-grade xanthate can be used for flotation. The adsorption product of xanthate on sphalerite is the zinc xanthate adsorption layer. 3. Xanthate Application in Copper Froth Flotation
Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This method of froth floatation is a method of mineral processing in which different minerals are separated selectively. Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by ...
