Answer. Copper is extracted from copper pyrites by froth flotation process. Froth flotation method is used to separate particles based on the differences in the ability of air bubbles to selectively attach to specific mineral surfaces in a mineral-water slurry. A finely crushed ore is suspended in water and a blast of air is passed through the ...

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.
An improvement in the froth flotation separation of metallic sulfide mineral ores, particularly those ores bearing copper and molybdenum, in which a mercaptan collector is used in an earlier primary flotation stage, the improvement comprising the addition of activated carbon to achieve deactivation of the mercaptan collector prior to the component mineral separation stage, thereby providing ...
More specifically, the improved process is a method for recovery of metal values by froth flotation from metallic sulfide mineral ores comprising copper and molybdenum, including the steps of A forming an aqueous mineral pulp from the ore B subjecting the pulp to rougher flotation to provide a scavenger feed and a rougher concentrate
What I claim and desire to protect by letters patent is 1. In the process of separating copper and molybdenum minerals from their associated gangue by subjecting an aqueous pulp of porphyry copper ore to a froth flotation process in the pressence of a gangue depressant and recovering the separated minerals as a flotation froth concentrate, the improvement wherein the depressant is a water ...
In some sulphide ores of copper, zinc and lead, the concentration is brought by froth flotation process. In this method, the advantage is taken of the preferential wetting of the ore by an oil. The finely ground ore is taken in a tank containing water and 1 of pine oil or turpentine oil.
The particle size of the particle and the froth stability, viscosity and pulp density during the process relevant factors during the process in the copper concentration process by flotation 2-5 Generally, flocculants and peptizes during flotation are applied to allow clays to be included into the pulp in suspended form. This reagent can ...
Apr 17, 2019 Embedded in a cloth of complicated Cu-Pb-Zn sulphide ore froth flotation process, the use of the potential regulation flotation technology of whole process priority, with lime slurry potential and adjustment to the LP - 01, SN - 9 aniline aerofloat and butyl xanthate were collecting copper, lead, zinc, and use a combination of zinc sulfate ...
Apr 11, 2019 Xanthate Application in Copper Froth Flotation. In the flotation process of copper ore, xanthate mainly reacts with Cu2. Therefore, when processing minerals containing more Cu2 on the surface, the effect of xanthate is stronger, and the order of its action is Cu2S CuS Cu5FeS4 CuFeS2. 4. Xanthate Application in Galena Froth Flotation.
The froth flotation of ore and coal is significantly improved in recovery and grade of valuable minerals and coal when a depressant combination of an inorganic sulfite and the salts of certain sulfonated compounds are employed.

Feb 06, 2020 For example, a copper and cobalt oxide mine in Congo, the main copper content is malachite, and the cobalt mineral is hydrocobalt. In order to improve the froth flotation process effect, the sodium thiohydride and ammonia sulfide was used to improve the effect of the froth flotation process in a 11 ratio. 2.
Feb 22, 2019 Correlation is used to find the process variables that affect the grade copper and recovery. Some of the factors that are studied as input variables are the copper grade of the ore at the entrance of the flotation process, the amount of reagents and foaming agent used, and the granulometry, among others.
Explain froth flotation process of copper pyrites. Copper is extracted from copper pyrites by froth flotation process. Froth flotation method is used to separate particles based on the differences in the ability of air bubbles to selectively attach to specific mineral surfaces in a mineral water slurry.
Corre lation is used to fin d the. process variables th at affect the grade copp er and recovery. Some of the factors that ar e studied as. input variables are the copper grade of the ore at the ...
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.
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 Graderecovery performance of a hypothetical copper ore flotation process.
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 smelting, and 4 electrolysis. Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is further processed at a mill ...
Froth flotation is a process that selectively separates materials based upon whether they are water repelling hydrophobic or have an affinity for water hydrophilic. Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
Keywords flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the ore is exploited Kabuda et. al., 2011.
Oct 12, 2016 Copper sulphate had a significant effect on the maximum froth height obtained in static three-phase froth tests. Proposals to explain these observation are made. If the above-mentioned thing is taken into consideration, the role of ceCuSO4 is to provide ceCu2 which will act as an activator in the manner explained above.
History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique. This technology has acclaimed importance as a versatile process for
Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.
The copper minerals and waste rock are separated at the mill using froth flotation.
