Recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. At the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver...

Delayed gamma rays following neutron activation, induced by a 6 MeV linear electron accelerator (linac) coupled to deuterium oxide photo-neutron conversion target, are simulated with MCNP6.1. The 1039 keV copper activation peak is detected 33 % relative efficiency hyper pure germanium detector. Two distributions were assessed for 2-hour irradiation followed counting configuration. Homogeneously...
