flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore [1]. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. Flotation Process | Encyclopedia.com.
flo·ta·tion / flt sh n / (also float·a·tion) n. the action of floating in a liquid or gas: the body form is modified to assist in flotation and propulsion. the process of offering a company's shares for sale on the stock market for the first time. the process of separating small particles of various materials by treatment with chemicals in water in order to make some particles adhere to air bubbles and rise to
From Simple English Wikipedia, the free encyclopedia. Jump to navigation Jump to search. Foam rich of solids produced during a flotation process. Flotation is a process where gas bubbles are injected at the bottom of a tank containing a mixture of a liquid and solid particles to separate the solid particles from the liquid.
flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic conditionthat is, the surfaces are either repelled or attracted by water. The flotation process was developed on a
flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore ore, metal-bearing mineral mass that can be profitably mined. Nearly all rock deposits contain some metallic minerals, but in many cases the concentration of metal is

As in coal flotation, oil agglomeration takes advantage of the difference between the surface properties of low-ash coal and high-ash gangue particles, and can cope with even finer particles than flotation.In this process, coal particles are

In philosophy it designates "a succession of phenomena presenting a certain unity or that are reproduced with a certain regularity." Andr é Lalande notes that the term is often used to refer to physiological, psychological, or social phenomena, and much more rarely to mental phenomena.

Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also processed by
Process, Process The term process is used extensively from within different perspectives, not all of which fall within the scope of psychoanalysis. The concep Flocculation, flocculation A process in which clay and other soil particles adhere to form larger groupings
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper 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 th
Sep 30, 2019· Dissolved air flotation ( DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.
Publisher Summary. Modern classification of flotation reagents is based on the function of a particular reagent. On this basis, reagents are divided into collectors, frothers, regulators, and depressants. Collectors are a fairly large group of organic chemical compounds, which differ in

Froth flotation, a process for separating hydrophobic from hydrophilic materials; Induced gas flotation, a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids; Flotation therapy, a technique whereby users 'float' in an isolation tank; See also. Float (disambiguation)
A series of actions, motions, or occurrences; a method, mode, or operation, whereby a result or effect is produced; normal or actual course of procedure; regular proceeding, as, the process of vegetation or decomposition; a chemical process; processes of nature. In patent law, an art or method by which any particular result is produced.
Dissolved gas flotation systems are used for a variety of applications throughout the world. The process floats solids, oils and other contaminants to the surface of liquids. Once on the surface these contaminants are skimmed off and removed from the liquids. Oil and gas production facilities have used flotation systems to remove oil and solids from their produced and processed water for many years.
In a number of cases, flotation tailings are not discarded but instead are used as construction materials and agricultural fertilizers. Flotation is the leading process for the concentration of nonferrous-metal ores. The use of recirculating water has been adopted, reducing the pollution of rivers and lakes.
sulphur (symbol S) Nonmetallic element in group VI of the periodic table, known since pre-history (the biblical brimstone).Essential to animal and plant life, it may occur naturally as a free element or in sulphide minerals such as galena and iron pyrites, or in sulphate minerals such as gypsum.The main commercial source is native (free) sulphur, extracted by the Frasch process.
A method of extraction developed for treatment of copper ores not amenable to direct flotation; the metal is dissolved by leaching, for example, with sulfuric acid, in the presence of an ion-exchange resin; the resin recaptures the dissolved metal and is then recovered in a mineralized froth by the flotation process.
flotation. 2. a process to concentrate the valuable ore in low-grade ores. The ore is ground to a powder, mixed with water containing surface-active chemicals, and vigorously aerated. The bubbles formed trap the required ore fragments and carry them to the surface froth, which is then skimmed off.
