Froth Flotation Seperation Of Flint From Coloured Glasses

Using three types of reagent it was possible to separate a 2g mixture of flint, amber, and green cullets selectively by flotation. On increasing the sample size to 50g and simulating the dynamic conditions of commercial process equipment, the total floatation response was similar but no selectivity was observed. This is attributed to the bonding of the flotation reagents being too weak to survive the dynamic conditions created.
