A laboratory study was conducted to evaluate and compare the effectiveness of nine different frother types when used in a three-phase, continuously operating froth flotation system. The frothers included several that are commonly used in the industry (e.g., MIBC, 2EH, and F-1) as well as unique frother types (e.g., F-3). The tests were conducted in a 5-cm diameter laboratory flotation column

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the

Introduction to Mineral Processing Chevron Phillips

A collector is a stone that attaches to the mineral surface and produces a hydrophobic (water-fearing) surface. While certain minerals are naturally hydrophobic and do not require a collector, recovery is often improved when a collector is used. This water-repellent film facilitates the attachment of the mineral particle to the air bubble. Many different chemicals are used as collectors

An overview of the use of stone reagents in mineral

Of the more specialised reagents, the largest volume chemicals are flocculants and coagulants, flotation frothers and sulphide mineral collectors. The most specialised high value reagents, although of lower volume, are solvent extractants. The more specialised reagents are predicted to increase in volume by 2–3% annually over the next few years.

Frothers Engineering360 GlobalSpec

Frothers are in many respects chemically similar to ionic collectors, and, indeed, many of the collectors, such as oleates, are powerful frothers, being in fact too powerful to be used as efficient frothers, since the froths which they produce can be too stable to allow efficient transport to further processing. Froth build-up on the surfaces of thickeners and excessive frothing of flotation

Flotation Reagents’ Types and Working Principles

Since most of the minerals in nature are hydrophilic, the flotation collector is widely used in flotation operations as a kind of flotation reagent. Generally, it can be divided into polar collectors and non-polar collectors. The commonly used collectors for flotation are mainly xanthate, dithiophosphate and thiocarbanilide, etc. Flotation Frothers
