Applied across the industry, improved coarse particle flotation can result in an additional million to million metric tons of annual copper production by 2032. If applied across all metals found in sulfide deposits, the technology represents potential value creation of 9 billion to 26 billion per year.

Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM. Uranium, which may be colocated with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice.
