For more than a century now, flotation has been at the heart of the mineral processing industry. In this month's SPOTLIGHT FEATURE ARTICLE, direct from the November issue of INTERNATIONAL MINING magazine, John Chadwick examines new technologies and applications from some of the key players in mineral flotation, a technique that is so important to the global industry.
Froth flotation is a method for separating hydrophobic materials (which will not mix with water) from hydrophilic materials (which readily mix with water). Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used ...
ABB Ability™ Expert Optimizer, ABB's Advanced Process Control () solution using straightforward design and deployment of model predictive control (MPC) with ABB Ability™ System 800xA DCS enables higher level of automation and optimization in a grinding and flotation circuit example.
Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
As froth flotation chemicals play a significant role in mining, extraction, and processing of these metal and mineral ores, expansion of the mining industry will accelerate the market growth.
Flotation Depressants. The mining industry faces many challenges, most notably lower quality reserves. With the decreasing quality of mined feed, more sophisticated techniques are needed to achieve industry required specifications. In many cases, the typical means of altering pH or applying different chemistries is not enough to offer the ...

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air …
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.
"Flotation 360 is a game-changing innovation," said Arjan Boogaards, senior vice president and general manager of Global Mining, Ecolab Industrial. "The solution is unique in its combination of advanced chemistry, technical expertise, digital innovation and predictive, actionable insights to achieve the highest level of flotation ...
For example, froth flotation is a technique commonly used in the mining industry. In this technique, particles of interest are physically separated from a liquid phase as a result of differences in the ability of air bubbles to selectively adhere to the surface of the particles, based upon their hydrophobicity.
Flotation collectors. Designed to operate across a broad range of alkalinity levels and provide faster flotation kinetics, our flotation collectors have become the industry standard in the recovery of copper, gold, molybdenum, lithium and other metals. AEROPHINE®, AERO® and AEROFLOAT® collectors (promoters) are used extensively for the ...
Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.
a flotation plant may outweigh all of the other uses of water at a mine site, and the need to maintain a ... International Mining, 2011) (see fig. 2). The mill operates in a closed circuit with screens that size the ore and cyclones that sort the ore by size and density. The underflow from the cyclones is sent back to the mill to be reduced ...
Mining-process waters become saturated with soluble salts after contact with minerals (oxidation and dissolution) during crushing, classification and flotation. Inorganic species, such as metal ions but also carbonate and sulphate ions, may have a positive or negative effect on mineral flotation.

Overview. The hydrometallurgical processing of copper sulfide ore - as well as other minerals, such as iron ores, etc. - starts with crushing it into a fine powder and then separating the valuable minerals by means of a flotation process. Volumetric flow measurements are required to maintain a proper process control and efficiency.
