However, the stability of the could be affected by other factors, including the presence of particles. For some specific conditions, it has been shown that frothers with different stability characteristics could be used in conjunction with flotation operating strategies to achieve similar froth recoveries results (Zanin et al., 2009 ...

Sylvinite ores are treated for removal of insoluble slimes by a froth flotation technique which includes flocculating the slimes with nonionic or polyacrylamide flocculants and thereafter utilizing a nonionic or an anionic flotation collector including a mixture of fuel oil or a fatty acid and a deer of the glycol ester or polyglycol ester type.

The flotation results gave a graphite concentrate with recoveries between 96.64% and 99.63% and grades between 78.13% and 90.88 %. Regarding the lithium metal oxides, these resulted in low recoveries in the concentrate between 9.47% and 16.57% and grades between 9.59% and 16.09%.
