Celanese The chemistry inside innovation
The decision to use a froth flotation process creates a range of options for a mine across collectors, modifier, and frothers. One significant choice for a mine using the froth flotation process is the selection of an optimal frother to generate quality froth and to maximize the recovery of

reagents. Flotation tests were also conducted with Appalachian coals for comparison. Iowa coals did not respond as well to froth flotation as Appalachian coals. Although Iowa coal floated very slowly and Incompletely with only a frother (methyl Isobutyl carblnol or MIBC), It floated rapidly when a

Since flotation frothers are used to reduce bubble size and increase froth stability, in the procedures adopted in this paper they were characterized by their ability to reduce bubble size in a

Abstract. Foams and froths are of considerable practical importance not only in froth flotation of minerals or in adsorptive bubbleseparation techniques applied to
(PDF) Flotation Frothers: Review of Their Classifiions
PDF The importance of frothers in flotation is widely acknowledged, particularly in terms of their role with respect to bubble size, and the stability and mobility of the froth phase. These
Froth Pumps for Froth Flotation, Mining, Paper/Pulp, and
In this sense, mining froth can be described as an aerated slurry that either occurs naturally or, in some cases, purposely created to assist with the separation of minerals. Froth flotation is an important step used for the recovery and upgrading of sulfide ores, allowing far more economic recovery of valuable metals from much lower grade ore.
Flotation Frothers Frothing Agents
SURFACE TENSION. Froth Flotation Frothers are chemicals used to strengthen the SURFACE TENSION of an air bubble. They do not create air bubbles. To demonstrate surface tension, fill a glass of water just prior to over flowing, you will notice that the surface of the water actually extends past the lip
The Effects of Frothers and Particles on the
It is evident, therefore, that the efficiency of flotation will depend on the use of frother to control bubble size, and hence particle collection in the pulp, and to stabilize the bubbles in order to exit the froth zone . 2][4]. The [use of frothers helps overall flotation performance by impacting both the quality (the grade) and quantity (the

AEROFROTH frothers include both alcohol and glycolbased products formulated for optimum effectiveness in all types of flotation systems. This complete line of products, in conjunction with unique collector/depressant chemistries together provide all of the tools for optimized flotation processes.
Evaluation of Frother Types for Improved Flotation
Froth stability and mobility are important factors that affect flotation recovery and grade. A froth that is too stable may prevent adequate drainage of the entrained material and is difficult to handle while an unstable froth is least desirable due to the negative effect on recovery and selectivity [].The frothers that are more efficient in reducing bubble size have been observed to produce

Nonvolatiles, from weak through to strong frothers The main purpose of frothers in froth flotation is to cost effectively reduce bubble size and stabilise the mineral laden bubble just long enough to remove it from the flotation cell with minimal detrimental effects on operability and grade/recovery performance.

Froth Flotation. Surfaceactive compounds that lower the surface tension of water and have the ability to adsorb on the air bubble–water interface. The effectiveness of some of the frothers is dependent on pulp pH. We carry MIBC & Pine oil.
TESTING FLOTATION FROTHERS
Froth flotation process commonly requires quite a large variety of flotation agents. Although it is believed that the most important are collectors, which are used to render valuable minerals hydrophobic, as the term froth flotation implies the process is inseparable from the froth. Froth generation requires the use of frothers which are
