How to Judge the Effect of Flotation Cell According to Flotation Froth ...

Flotation cell operators usually take the "virtual and real" of flotation froth as the basis for judging the degree of mineralization. If the mineral particles attached to the surface of the froth are many and dense, it is "real"; if the mineral particles attached to the surface of the froth are few and thin, it is "virtual".

copper oxide flotation|miningpedia

Jul 27, 2021Froth flotation is a method of separating ores using the difference in physical and chemical properties of mineral surfaces. It is currently the main method for the flotation of copper oxide. Relatively speaking, froth flotation can be used to separate malachite and azurite. However, chrysocolla and copper phosphate are difficult to float.
