The basis of this enrichment process is the difference in the densities of the minerals that make up the original raw material.
When such a mechanical mixture is immersed in a liquid with an intermediate density, the waste rock floats, while the metal-containing minerals, being heavier, sink.
Hence, the main emphasis in the development of such a high-precision enrichment process was placed on finding the optimal formulation of such a water-based working medium in close connection with the justification of a simple and energy-efficient procedure for its complete regeneration from the enrichment products and its return to the head of the process
