copper oxide flotation|miningpedia

2021-7-27  Froth 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.
