Flotation Method Research on Fine-particle Copper Oxide Minerals

Fine-grain disseminated copper oxide minerals are very difficult to float in production due to its special nature. Vacuum tube flotation tests were carried out using malachite pure mineral with different size fractions, and it was proved to be one of the most effective ways to recover the fine-particle copper oxide minerals through the comparison of the results between Vacuum tube flotation tests and Hallimond tube flotation tests.
