Suspending the crushed ore in water and passing air through it. Addition of pine oil to the mixture to separate ore from gangue particles. The air bubbles attached to the wet particles act as froth and float at the top due to being lightweight. Skimming and separating the froth from the gangue. Obtaining the metal after drying.

Flotation Froth. Flotation (froth flotation) is widely used in the mining industry to separate valuable mineral particles from gangue material in crushed and ground ores, based on the ability of air bubbles to selectively adhere to specific mineral surfaces. From: Journal of Cleaner Production, 2013. View all Topics. Add to Mendeley.
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.
The meaning of FROTHER is an agent (as pine oil or cresol) that is active in froth flotation through its ability to change the surface tension of a liquid and consequently decrease the wettability of the particles to be recovered.

Application to Commercial Flotation Processes Film Flotation. Pulp with or without oil or acid is fed gently, at an acute angle, onto the surface of a body of still water. The sulphide floats and the gangue sinks. Possible cases: Case 1.—Sulphide, gangue, water. Case 2.—Sulphide, gangue, water, oil. Case 3.—Sulphide, gangue, water, acid.

The froth of a flotation column is usually . water washed, with approximately as much wash water as there is water reporting to the froth. The water is most commonly added via pans, perforated with 4-8 mm diameter holes, located 20-30 cm above the froth, thus generating a "rain" of water onto the surface of the froth.
Froth flotation is the most widely used separation process in modern paper mills. During the last 10 years, the development of flotation de-inking cells has been pursued more aggressively than the technologies of any other segment of the pulp and paper industry. Initially, Denver flotation cells used in the mineral industry were installed in ...

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.
In flotation dry-crushed ore gives poor separations, and wet grinding is essential to secure effective wetting and sinking of the unwanted gangue particles. After passing through the grinding section, the resulting pulp must conform to two conditions. Firstly, the particles of ore must be as nearly as possible of the size required for flotation.
