METALS RECYCLING IN EEE WASTE-2
SECONDARY COPPER (Cu) RECOVERY
5-40% Cu containing electronic scrap are fed into a blast furnace. Cu-compounds have to be reduced by scrap Fe and plastics. Sn, Pb and Zn impurities are also reduced as gas fumes.
Energy needed to reclaim Cu from EOL e-waste is only one sixth of the energy that would be required to produce from Cu ore.
