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.
Froth flotation is a process used to separate minerals, suspended in liquids, by attaching them to gas bubbles to provide selective levitation of the solid particles. It is most extensively used process for the separation of chemically similar minerals, and
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 concept of froth crowders and was developed in the early 1950s. The need for crowding froth out of a flotation cell grew along with the size of flotation machines and their cells.. The 1st froth crowder device was patented in 1956 (Fig 1 and Fig 2). What I call the crowder plate is Piece/Item # 12 on the drawings below.

The process of froth flotation for upgrading the quality of coal by removing mineral matter (ash and pyrite) has received increased attention since the 1960s. The froth flotation process is typically used for treating <0.5-mm size coal and is currently the only technique both effective and economical to clean coal on a commercial scale.
Since froth stability plays a critical role in determining the performance of flotation operations, there is an urgent need to study the effect of frother dosage and seawater on froth stability. In this study, flotation tests in seawater were conducted to examine the effect of frother's dosage (MIBC) on the froth stability and flotation ...
Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper …
Froth flotation is a physicochemical separation process based on the differences in surface properties of materials. This technique was primarily developed for mineral beneficiation and has been widely used in mineral processing for over a century to separate desired minerals from their associated gangue (unwanted minerals).
Research highlights Literature of instrumentation used in flotation control. A review of base-level (regulatory) process control in froth flotation processes. A review of stabilising flotation control, and optimising flotation control methods. Review of implementation of 'newer' technologies into flotation process control including machine …
Froth Flotation is a mineral processing process achieving solid-solid separation by taking profit of the chemical attribute leading to the possibility of selectively controlling the relative surface hydrophobicities of the various components mixed in an aqueous medium. Froth flotation is the most common industrial process based on this …
Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphtha-based hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic …
This review aims to offer a comprehensive overview of the importance of frothers in the flotation process focusing on their performance and function in the …
Froth flotation is an important concentration process that can be used to selectively separate hydrophobic materials from hydrophilic waste gangue. In a more simple …

The method of froth floatation is used to separate metal ores. Let us learn about the meaning of froth floatation.
The operation of the process is affected by the mineralogical character of the ore, the grade of feed, the kind and quantity of flotation agent and, to a less extent, by the temperature of the pulp, the place and method of adding the flotation agent, the type of flotation machine used, and the method of removing concentrate.
3. Flotation is a physico-chemical separation process that utilises the difference in surface properties of the valuable minerals and the unwanted gangue minerals. 1. Selective attachment to air bubbles (or "true flotation"). 2. Entrainment in the water which passes through the froth. 3.
