May 15, 2019 Flotation frothers, also known as flotation foaming agent, is an essential flotation agent for froth flotation.The role of flotation frothers is mainly to produce a large amount of foam in the pulp, so that the available minerals are effectively enriched at the interface between air and water to create the conditions required for flotation process.The quality of flotation frothers directly
In this paper, a scheme of flotation frothers classification is presented. The scheme first indicates the physical system in which a frother is present and four of them i.e., pure state, aqueous solution, aqueous solution/gas system and aqueous solution/gas/solid system are distinguished. As a result, there are numerous classifications of flotation frothers

properties of the strong flotation frothers. The former can be used in flotation of very fine particles, whereas the latter will provide higher recoveries and better performance in floating of coarser particles. Comparison with Fig. 4 explains that those which are selective are characterized by small DFI and large CCC values, while the powerful

Frothers may act to stabilize air bubbles so that they will remain well-dispersed in slurry, and will form a stable froth layer that can be removed before the bubbles burst. Ideally the frother should not enhance the flotation of unwanted material and the froth should have the tendency to break down when removed from the flotation apparatus

Flotation is carried out at a pulp density of from about 15 to about 40 percent solids. Acidity in the pulp is controlled to provide a pH range of from about 7 to about 12. The frothers are employed with any of the standard collectors such as xanthates (e.g., ethyl xanthate), dithiophosphates, phosphocresylic acids, or diphenyl thiourea

Froth flotation is widely used for upgrading of ores and other materials. Efficiency of flotation depends on many parameters, including type, chemical structure and dose of flotation reagents. Selection of a proper frother in flotation depends on the material used, necessary dose of frother and its selectivity

Frothers & Froth Flotation. The importance of frothers in mineral flotation is widely acknowledged in the mining industry. Frothers perform the following key functions in the froth flotation process: Reduce surface tension of the liquid-gas interface to enable froth formation; Hinder coalescence in order to stabilize bubble size

Frothers are non ionic surfactants, commonly alcohols and polyglycols, used to provide two functions in flotation, namely to reduce bubble size and stabilize froth. Both functions imply an impact on the properties of the air-water interface (bubble surface) but there is no consensus on the mechanism, particularly with regard to bubble size reduction

Introduction The froth phase plays an important role in the recovery of minerals and the produc-tion of concentrates in the flotation process. The flotation zone includes two parts of col-lection (pulp) and froth zone, and the perfor mance of each section can be considered sep

Jun 22, 2015 To handle this coalescence, a broad family of non-ionic surfactants, denoted as frothers in the flotation literature, is used. Frothers control the dynamic surface tension involving the bubbles, thereby preventing bubble coalescence from occurring to the same extent as without frother. The proper choice of frother chemistry can lead to significant differences in the bubble size distribution present in
