Froth stabilizers Reagents which are used to increase the life time of the froth (to prevent the froth from going into the solution again) are known as froth stabilizers.

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10].

The froth flotation of coal is conducted in the presence of a conditioner of an oxygen containing compound of the formula: R₁ O-R₂) n (I) wherein R₁ and each R₂ are independently saturated hydrocarbyls and n is 1 to 3. EP0290283A2 - Method for the froth flotation of coal - Google Patents ...

Froth flotation represents the most versatile separation method in mineral processing. It takes advantage of the different surface minerals properties to selectively separate more hydrophobic minerals from less ones towards interactions with air bubbles. Flotation has been initially developed to treat the sulfide minerals of copper, lead, and zinc.

The depletion of ore deposits, the increasing demand for raw materials, the need to process low-grade, complex and finely disseminated ores, and the reprocessing of tailings are challenges especially for froth flotation separation technologies. Even though they are capable of handling relatively fine grain sizes, the flotation separation of very …

The froth flotation technique can be considered one the most effective methods for beneficiation of carbonate salt-type minerals. While the flotation separation of Mg carbonates from non-salt-type minerals is relatively efficient, the beneficiation process is significantly more difficult when salt-type minerals are associated. ...

Condensation products of a fatty acid or fatty acid ester and a hydroxyalkylated polyalkylenepolyamine are useful as conditioners to improve the recovery of clean coal in a froth flotation process. The presence of these condensation products in the flotation medium is particularly effective to enhance the recovery of oxidized bituminous coal.

2. Flotation column in a nutshell A froth flotation cell consists typically of a collection zone (or pulp zone) located below the feed particle point, and a cleaning zone, (or froth zone), above the particle feed point [26] (Figure 2). The collection zone is fed back-stream by the pulp pushed by the bubble swarm created by a gas
