Flotation Developments & Best Practice. Posted by Daniel Gleeson on 4th November 2013. Prof Graeme Jameson is a nominee in the International Mining Technology …
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 …

The emergence of pneumatic flotation technology has revolutionized mineral processing, offering a more efficient and effective approach to separating valuable minerals from gangue. These cells utilize forced air and slurry mixtures at high velocities to create bubbles, eliminating the need for mechanical agitation.
In the flotation process, a mixture of water, minerals, and a flotation agent (also known as a collector) is agitated to create a stable froth of bubbles. The flotation agent helps to form a stable froth of air bubbles, which attach to the mineral particles and cause them to rise to the surface, where they can be collected.
1. Introduction. Mining activities consume billions of m 3 of water annually. The water withdrawn by mining industries could achieve 17 m 3 per ton of processed ore while the water consumption required in processing varies between 0.34–6.27 m 3, according to data from 359 industries reports [1].Seeing that the world iron ore production was 2537 million tons in …
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a …
Mechanical and pneumatic flotation cells are the most widely used in mineral processing. Mechanical flotation cells utilise an impellor to agitate the slurry and produce turbulent regions for bubble particle attachment, whereas in pneumatic flotation cells pulp and air are introduced together into the cell through a nozzle, also termed a ...
The accolades are an acknowledgement of Jameson's groundbreaking flotation technology, the Jameson Cell. The technology, which was made available in the late 1980s after 20 years of research, enables the mining industry to create billions of dollars of extra value by using bubbles to capture super-fine particles of less than a hair's breadth during mineral …
Froth flotation is a selective separation process to separate valuable materials (recyclables, minerals, and other fine-size waste) from unwanted materials (gangue) using air bubbles in a general floatation tank, Jameson flotation cell, or flotation column. From: Recycling and Reusing of Engineering Materials, 2022
The REFLUX™ Flotation Cell (RFC™) combines several technologies to achieve superior flotation performance at a magnitude far beyond the capacity of existing flotation devices. This technology was …
Separation of mineral particles by flotation takes advantage of the wettability contrast between the surfaces of different mineral particles. In a flotation pulp, hydrophobic particles attach to air bubbles forming aggregates which float to surface of the cell, and form a layer of froth (Drzymała and Swatek, 2007), while hydrophilic particles ...

Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.
As separation efficiency of a single flotation cell is limited, multiple cells are used to improve the recovery of valuable minerals. Flotation performance matters. In today's mining environment, every percentage …
