Flotation Reagents & Collectors Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals.
It is well known that the solid content of the flotation pulp is an important parameter in the flotation of sulphide ores, so flotation experiments were carried out at different solids concentration (15–40%) in the Denver flotation cell to determine its effect on the Cu recovery and grade.
The effect of copper activation and galvanic interaction on the behavior of free gold and refractory gold during froth flotation were studied by some researchers (15 Teague , A.J.; Van Deventer , J.S.J.; Swaminathan , C. ( 1999) The effect of copper activation on the behaviour of free and refractory gold during froth flotation.
A collector composition for use in froth flotation processes comprises two collectors. One of the collectors is preferably an omega-(hydrocarbylthio)alkylamine, S-(omega-aminoalkyl) hydrocarbyl thioate, N-(hydrocarbyl)-alpha, omega-alkanediamine, (omega-aminoalkyl) hydrocarbon amide, omega-(hydrocarbyloxy)alkylamine, omega …

the frother (3). Similarly, the stable froth height parameter reflects the sum of hydrodynamic conditions in the froth, i.e. the effect of bubble size undergoing coalescence plus the influence of the water in the lamellae and Plateau borders between bubbles.
Effect of microemulsified collector on froth flotation of coal by L. Li*, X. Lu*, J. Qiu*, and D. Liu* Synopsis The performance of microemulsified diesel and conventional diesel collectors in coal flotation was compared by flotation indicators, including combustible recovery, ash content of the clean coal, and the flotation index.
In this study, the effect of pulp temperature on coal flotation was investigated. Waste vegetable oil was used as collector. Experiments were carried out at different temperatures (5, 25, 50 and 75 °C) and the pros and cons of each temperature for flotation performance were revealed.
Figure 1: The flotation system includes many interrelated components, and changes in one area will produce compensating effects in other areas (Klimpel, 1995) Froth flotation is a good example of an engineering “system”, in that the various important parameters are highly inter-related, as shown in Figure 1.
The effects of the CC and BF on the froth stability and flotation performance (i.e., recovery and selectivity) were investigated. The results show that only 44.51% recovery with …
Thus, in summary, with the rate depressing phenomena of increasing collector dosage, the difference between a “high” rate collector and a “low” rate collector is merely the starting value of the K’s associated with each collector at low dosages.
Present work focuses on the differences in the performances obtained in the froth flotation of copper smelter slag with multiple collector viz. sodium iso-propyl xanthate (SIPX), sodium di-ethyl dithiophosphate (DTP) and alkyl hydroxamate at various dosages.
For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or …
