Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Flotation Mineral Processing & Metallurgy

The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical operations

06/08/2010· The flotation process depends on several design and operational variables. We consider a superstructure that includes the following three flotation stages: the rougher, which processes the feed; the cleaner, which generates the final concentrate; and the scavenger, which generates the final tailing, as shown in Fig. (1).This is a simple superstructure but is used here as an example.

Flotation ScienceDirect

In 2005, flotation celebrated its 100th anniversary since the first commercial introduction in Broken Hill in 1905. Since then, flotation has grown to be the prime mineral processing operation for both hard rock and coal separations. Flotation is a separation process that has found prominence because of the need to treat complex or low-grade ores where the average particle size for liberation

The Importance of pH in Flotation

In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new stone substance called a BASE. This is very important. The ore may be either alkaline or Acidic. To have a positive control over flotation, it is necessary to be

Flotation Froth an overview ScienceDirect Topics

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. However, this process is based upon density

Flotation Reagents Mineral Processing & Metallurgy

Flotation as a concentration process has been extensively used for a number of years. However, little is known of it as an exact science, although, various investigators have been and are doing much to place it on a more scientific basis. This, of course, is a very difficult undertaking when one appreciates how ore deposits were formed and the vast number of mineral combinations existing in

Column flotation simulation and control: An overview

Column flotation control is often seen as a problem that cannot be handled by standard feedback control techniques. Such a vision certainly put a curb on a major breakthrough in column control. Most of column flotation control issues are instrumentation matters, related to the lack of commercial sensors to monitor key process variables

Important to the flotation process is controlling the surface tension of the interface among the bubbles, the aqueous solution, and the hydrophobed particles. This is achieved by a combination of the design of the flotation machine (called a flotation cell) and the use of a second class of surfactants known as frothers. In a simplified sense, the role of the flotation machine is twofold:
