Froth flotation is the separation of minerals that differ little in density but substantially in wettability by surfactants that stabilize a froth produced on the surface of an agitated solution of the minerals in water.
Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). ... Amine collectors are also effective at floating cyanide-depressed pyrite in alkaline solutions, although the flotation rate is slow (Ramsay, 1978; Broekman et al., 1987).
Froth flotation has been the most important technological invention to provide humankind with the metals required. However, ores have become leaner and more complex to process, challenging our long-held technological solutions.

Froth flotation. Flotation comprises two entirely different types of processes which resemble each other only in the fact that in both the concentrate is removed in the …
Froth flotation is widely regarded as one of the most efficient and economical methods for separating ultrafine particles. Froth flotation is a chemico-physical separation process …
What Is Froth Flotation? Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used ...
A special nanobubble generation system has been developed for evaluating the effect of nanobubble on froth flotation. In this study, an eight-factor five-level Central Composite Experimental Design was conducted for investigating eight important parameters governing the median size and the volume of nanobubbles.
The froth phase is the main component of froth flotation as it defines both the quality of the end product and the overall efficiency [148]. ...

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an …
Solutions which form froth are preeminently aqueous solutions and the properties of the liquid film are only secondarily determined by those of the gas. The durability of a liquid film depends …
Nowadays, froth flotation of chalcopyrite ore has developed a large number of reagents that make it possible to improve the mineral's buoyancy conditions, both in the presence of ions that simulate the use of seawater or process water, and in conjunction with other minerals.
Hydrocarbon gases are known to dissolve in surfactant solutions and affect the solution/gas interfacial properties. In this study, their effect on the froth flotation of various minerals was investigated.
Froth flotation of high-iron marmatite particles activated by ammoniacal copper(II) solution has been studied in this work. This study was performed on single marmatite mineral of 76–125 μm in size and 20% iron content by using micro-flotation.
Chapter 12 Froth Flotation Flotation is undoubtedly the most important and versatile mineral separation technique, and both its use and application are continually being expanded to treat greater tonnages and … - Selection from Wills' Mineral Processing Technology, 8th Edition [Book]
Froth flotation is the most important technology applied around the world to separate fine mineral particles in aqueous suspension. Froth flotation is …
Internal elements such as launders and crowders are cost-effective inserts that improve froth recovery and facilitate froth transport in large flotation tanks. Although internal elements have emerged as the most promising solution for froth transport problems, their design and scale-up has not been thoroughly studied.
In froth flotation, air is bubbled through an aqueous solution or slurry to which a ing agent (soap) has been added. The air-soap bubbles carry finely dispersed solids and hydrophobic materials such as grease and oil to the surface where they can be …

Flotation is based on chemical phenomena occurring at the interfaces, solid/water and air/water. Surface Chemistry principles have played a significant role in the development of flotation technology. Knowledge of aqueous solution chemistry and electrochemistry has added to our understanding of the reactions in flotation systems.
The process of froth flotation is an outstanding example of applied surface chemistry. It is extensively used in the mining, mineral, metallurgical, and chemical industries for separation and selective concentration of individual minerals and other solids. Substances so concentrated serve as raw materials for producing appropriate metals …
Froth flotation chemistry can significantly impact the flotation process, from preventing bubble coalescence, to stabilizing bubble size and particle adhesion, to increasing bubble residence time and surface area flux. Today's rapid froth flotation processes rely on alcohol- and polyglycol-based chemistries.
