This work proposed a novel method of pyrolysis and vacuum metallurgy to recycle gallium and arsenic from GaAs-based e-wastes, which may cause arsenic contamination and gallium waste if treated improperly. As a typical GaAs-based e-waste, the light-emitting diode (LED) was studied in this paper. Pure GaAs chips were first adopted to study the vacuum separation behavior of gallium …
