frothing properties of aminefrother combinations

Jan 01 2012 Froth flotation is a surface chemistrybased unit operation that involves the capture of hydrophobic particles by air bubbles in aqueous slurry followed by levitation and collection in a froth layer Conversely because hydrophilic particles do not adhere to air bubbles they are likely to sink and go to the underflow of the flotation cell 3 Jan 07 2019 Methods to determine frother functions control of bubble size and froth properties are now widely used Some collectors also exhibit frother functions which are less understood Using a waterair system in a minimechanical flotation cell setup this paper determines bubble size and water overflow rate for three amine collectors one primary amine dodecylamine DDA and two commercial

Feb 01 2003 The objective of this project was to compare the effect of a selective flotation frother MIBC and powerful frothers DEMPH and DF1012 on bubble size and foamability in water and in brine In water the bubble size is clearly reduced by flotation frothers which prevent bubbles from coalescing The present study shows that the bubbles do not coalesce in brine and therefore frothers The cell flotation experiments show that before surface dissolution an optimal concentrate with 212 TiO2 and 783 recovery is achieved using 1000gt sodium oleate 100gt PbNO32 activator and 80gt quebracho depressant
