copper floatation and gold separation

Effects of particle size on flotation performance in the ...

2019-2-15  Therefore, in all the experiments of copper-lead separation flotation and gold-lead separation flotation, the separation efficiency of the intermediate size fractions is the highest. A lower SE value of gold-lead for the coarse size fraction may be due to insufficient liberation of gold from galena or other gangue minerals.

Advances in Coarse Particle Flotation - Copper and Gold

To achieve an efficient separation in the flotation process, valuable particles need to be selectively segregated from the gangue while utilising a minimum number of flotation stages. Today's existing flotation technologies are effective for fine particle size classes; however, limitations due to particle buoyancy and bubble-particle detachment restrict the effectiveness of traditional ...
