Method of separating individual cathode active materials from a mixture of cathode active materials by froth flotation has been developed. They are based on using appropriate chemical reagents that selectively hydrophobize individual cathode active materials to be recovered, so that they can be collected by air bubbles used in flotation and separated from other mixtures. The chemical reagents are amphiphilic molecules with specialized head groups have a strong affinity to metal elements on surfaces of cathode materials. This method enables a separation of individual cathode active material from a mixture of cathode active materials.
