Copper sulphate is frequently helpful in accelerating the flotation of pyrite and arsenopyrite. In rare instances sulphuric acid may be necessary, but the use of it is limited to ores containing no lime. ... Frothers and Froth Modifiers. The commonly used "frothers" are steam-distilled pine oil, cresylic acid, and higher alcohols. The third ...

To help towards an understanding of the reasons for the employment of specific types of reagents and of the methods of using them, an outline of the principal theoretical factors which govern their application may be of service. For a full discussion of the theory of flotation the various papers and text-books which dea…
Factors affecting froth floatation Particle Size in Grinding. Both large and tiny ore particles have an impact on flotation efficiency and mineral recovery. Because of their heavy weight, flotation coarse particles are difficult to suspend in the flotation machine, and the chance of collision with the bubbles is reduced.
The operation of a froth flotation column can be described by a nonlinear convection–diffusion partial differential equation that incorporates the solids–flux and drift–flux theories as well as a model of …

The ores are concentrated through froth flotation in the form of copper-sulfide or copper-iron-sulfide minerals (e.g. chalcopyrite, chalcocite and etc.), which are then melted in a high-temperature reheating furnace (± 1250 ℃). ... The floatation of CuS increases when its surface is slightly oxidized, which is attributed to Reaction (3) and ...
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) …

Flotation (froth flotation) is widely used in the mining industry to separate valuable mineral particles from gangue material in crushed and ground ores, based on the ability of air …
Froth flotation is part of a copper beneficiation process in which finely ground ore is placed in aerated tanks that contain a water-based solution from which a copper-sulfide-rich …
After 3 minutes the froth was allowed to overflow and the float was kept at constant level mark (10mm below overflow lip) using distilled water from a wash bottle. Samples of the froth concentrate were collected after every 5minutes for 20 minutes. The collected samples were then sun-dried, weighed and assayed for nickel, cobalt and copper.
Flotation was first performed in 1860 (Arbiter, 2000) and is a technology that utilizes the differences in physicochemical properties of various mineral surfaces to achieve specific separation (Wills and Munn, 2005), as depicted in Fig. 1.This process involves hydrophobic particles adhering to air bubbles being transported to the froth layer, …
Here potassium ethyl xanthate acts as a collector. $ce{KCN}$ and $ce{NaOH}$ depress the floatation property of $ce{ZnS}$ and $ce{FeS2}$ particles. Thus, only $ce{PbS}$ particles go into the froth. Now copper sulphate is added to the mixture which activates floating character of $ce{ZnS}$ and this time only $ce{ZnS}$ …
1. Introduction. Today, the flotation method, in which many parameters are effective, remains one of the most significant enrichment methods. According to Nagaraj …
After the copper ore is crushed, liquid is added to make it a slurry. The slurry is a mix of valuable copper ore minerals and "worthless" rock, called gangue (pronounced "gang"). The slurry is placed in a tank and a process called froth floatation is used to separate the copper minerals from the gangue. Chemical reagents called ...
Several attempts have been done, aiming to recover copper from flotation tailings through mainly acid leaching [17], and froth flotation [4].Using the latter, the recovery of copper through reprocessing of tailings has been studied both in the laboratory and on the pilot scale with an emphasis on the concentration of reagents and a pre …
The primary ore of copper will be copper pyrite and copper is separated from this ore. The various strides in extraction of copper are: Crushing and Concentration: The metal got from mines are separated into little pieces by jaw smasher and afterward pulverized. The ore being sulphide mineral is concentrated by floatation process.
The Problem with Copper for Porphyry ores and Chalcocite and Chalcopyrite Copper, one of our most important minerals, is found in many parts of the world. One of the major sources of Copper is the so-called porphyry ores such as the large deposits in the west and southwestern United States, Mexico, South America and …

A survey of plant operations (O'Connor and Dunne, 1991) revealed that many flotation operators observe that copper sulfate addition appears to influence mainly the froth stability and that there is an optimum dosage – too little resulting in high slime recoveries and too much resulting in froth instability (O'Connor et al., 1990).
Froth stability is a critical factor for flotation and even a small decrease in froth stability causes a decrease in the recovery of desirable minerals (Hadler and …
