The Effects of Frothers and Particles on the Characteristics of Pulp ...

Froth is an integral part of the flotation system but despite the importance, relatively few studies have been conducted to examine the impact of froth variables (e.g. bubble size, frother type and concentration, liquid/gas/solid content) on the performance of flotation cells 21]-[25].

Applications of CO2 in CO2-responsive foams and pyrochlore froth flotation

In micro-flotation testing it was found that at a pH of 4, the use of CO2 led to recoveries of pyrochlore and the gangue minerals quartz and microcline that are comparable with the recovery achieved when oxalic acid or HCl are used. The promising outcome of the micro-flotation tests were replicated in a batch flotation setup with real ore.
