As copper recovery declines, so does the tellurium supply ...Most refined tellurium is recovered as a byproduct from the electrorefining of copper. In a 2017 report, the USGS calculated that the world currently depends on copper mining for roughly 90% of its tellurium supply. However, as copper grades continue to decline, copper miners are turning to different recovery methods to exploit lowergrade ore.
copper flotation ore The development of froth flotation has improved the recovery of valuable minerals, such as copper and lead bearing minerals. Along with mechanized mining, it has allowed the economic recovery of valuable metals from much lower grade ore than previously. Get Price Copper Flotation Mineral Processing Metallurgy.
