Frother partitioning in dual-frother systems: Development of analytical technique

International Journal of Mineral Processing, 2013
Abstract Dual-frother blends are becoming popular in flotation practice. There is no work showing how frothers in the blend partition between the pulp and froth zones. In this paper two methods, high pressure liquid chromatography (HPLC) and a novel proton nuclear magnetic resonance spectroscopy (1H NMR) associated with total organic carbon analysis (

Mapping frother distribution in industrial flotation circuits

Minerals Engineering, 2017
Abstract Bubble size, which controls flotation kinetics, is strongly dependent on frother concentration. Frother concentration variations occur in operations due to the complexity of some circuits and the demands to deliver a reagent at part-per-million levels.

Frother Analysis in Industrial Flotation Cells

Canadian Metallurgical Quarterly, 2010
AbstractFlotation is a separation process based on the collection of particles on the surface of bubbles. Flotation machines disperse air into bubbles using a variety of techniques. The characteristics of the bubble population are strongly affected by the selection of frother type and concentration.

Frothers and Frothing

Minerals Engineering, 2018
Frother molecules have uneven distribution of polar and nonpolar groups which enables them to preferentially orient at water/air interface. There are three main groups of reagents employed by the mineral industry as frothers: alcohols, alkoxy-substituted paraffins and polyglycol-type frothers.

Frothers: Plant Practice

Mineral Processing and Extractive Metallurgy Review, 1989
Abstract This paper summarizes current plant practice involving frothers. Included is a brief review of the several mechanisms proposed for froth formation and particle-bubble attachment and discussion of frother-collector surface complexes, important practical attributes of frothers, the effect of collector on froth properties, the importance of ...

Frother analysis: Some plant experiences

Minerals Engineering, 2007
A colorimetric technique, originally developed for methyl iso butyl carbinol (MIBC) based on the Komarowsky reaction, has been extended to a wide range of common mineral flotation frothers. The procedure, which is briefly described, is suited to on-site determination as shown in a series of industrial case studies.
