Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

Flotation Froth

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10].

Differences in surface qualities between the minerals inside the flotation pulp become obvious after reagent treatment, and for flotation to occur, an air bubble must be able to attach itself to a particle and ...

Principles and practice of sulphide mineral flotation

The practice of sulphide minerals flotation is as old as the flotation process itself. In the United States, for example, the first froth flotation plant began operation in 1911 at the Butte and Superior Copper mill in Basin, Montana and recovered sphalerite from slimes (material 92% finer than 150 meshl.I Although in 1911

Fundamentals of froth flotation | ChemTexts

Theoretical and experimental investigation of disodium

NaHS is the predominant reagent used to depress copper and iron sulfides and thereby enable molybdenum flotation recovery and grade. However, these inorganic reagents have increasing regulations governing their use and have high consumption rates collectively meaning that the use of alternative reagents, especially organic depressants, …

How to Determine A Reasonable Flotation Agent System

Most flotation plants use a copper and molybdenum suppression flotation scheme during the separation of copper and molybdenum mixed concentrates, mainly because of the higher quality of the ...

Use of chelating agents as collectors in the flotation of copper

The flotation of malachite is generally similar to that of the copper sulfides, indicating the special effectiveness of copper in the crystal lattice for collector attachment. Fourteen reagents that are potentially capable of chelating with a metal ion on the surface of the major copper sulfide minerals and pyrite were evaluated

Floatation | PPT

4. INTRODUCTION Flotation is the separation of particles from a mixture by causing some particles to collect on the surface of bubbles. Floatation is an extractive process where various minerals can be selectively extracted. For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cu and Zn. The …

Flotation Froth

The indispensable tool for Cu concentrate production is froth flotation (Fuerstenau, Jameson, & Yoon, 2007). This technique is used to upgrade an ore to a concentrate by selectively floating copper-containing minerals away from non-copper minerals. The principles of froth flotation are as follows: (a)

The Challenges and Prospects of Recovering Fine …

sulfide ores are usually produced by flotation and then processed by pyrometallurgical or hydrometallurgical methods to extract the copper [3,9,10]. Froth flotation is widely used to separate sulfide minerals from gangue minerals such as quartz (SiO 2), based on the surface properties of minerals. The principle of the flotation

Insight into mineral flotation fundamentals through the DFT …

The surface is the contact region where many adsorptions occur during the flotation process. Unlike these of stable coordination composition in the bulk structures, the atoms of the surfaces tend to form different terminations due to the breaking of the fracture bonds [33].Therefore, the surface structure has very different atom states from the bulk, …
