- Copper Flotation Cell Beneficiation
Among beneficiation techniques, froth flotation is the most well-established technique to concentrate RE minerals and can process a wide range of fine particle sizes. Due to the difference in hydrophilicity between RE minerals and associated minerals, flotation reagents are added to achieve separation.
