Flotation Separation Froth

Flotation | ore dressing | Britannica

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 commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.

Froth flotation | ore dressing | Britannica

Froth flotation, separation of minerals differing little in density but greatly in wettability by surfactants that stabilize a froth formed on the surface of an agitated suspension of the minerals in water. See flotation. This article was most recently revised and updated by Erik Gregersen, Senior Editor.

In view of the problems associated with the safe disposal of plastics waste, the efforts are being made to find efficient ways of recycling this waste The mon mineral separation processes such as classification, heavy media separation and froth flotation can be utilized in the separation of plastics

Introduction to Mineral Processing - Chevron …

Frothers are liquids that produce the froth or foam on which the flotation process depends. The froth resembles soap suds and provides the physical separation between the mineral(s) floated and the pulp containing the waste. The froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and non-flowing.

Froth Flotation Method - JXSC Machine

The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons: (1) In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings, thus reducing the smelting cost.

Froth flotation - kruss-scientific.com

Froth flotation Optimization of flotation separation using interfacial stone methods. Flotation has become established as an efficient solid-liquid separating method in ore processing and for the separation of colored pigments (de-inking) in stone recycling.

Dissolved air flotation - Wikipedia

A very similar process known as induced gas flotation is also used for wastewater treatment. Froth flotation is commonly used in the processing of mineral ores. In the oil industry, dissolved gas flotation (DGF) units do not use air as the flotation medium due to the explosion risk. Nitrogen gas is used instead to create the bubbles.
