· In the present study, a model of closed-loop recycling of copper from PCBs is demonstrated, which involves the sequential application of bioleaching and electrowinning to selectively extract copper. This approach is proposed as part of the solution to resolve the challenging ever-increasing accumulation of electronic waste, e-waste, in the environment.
· E-waste recycling services are provided across metropolitan, regional and remote Australia as part of the Australian Government’s National Television and Computer Recycling Scheme. This industry-funded scheme makes it easier for people to have their televisions, computers, printers, computer parts and accessories recycled for free.
Gold is one of the most valuable and precious metals. But, the extraction efficiency of gold from natural resources is very low and labor-intensive due to very low concentration of gold, i.e., 1–5 ppm, which means that gold extraction processes produce extensive amounts of tailings. The gold content in printed circuit board (PCB) of waste mobile phone is about 100–400 ppm, which is
· Recycling of e-waste through appropriate technologies is, however, considered to be a profitable business as the printed circuit boards (PCBs) contain the precious metals (including gold, silver etc.). The present recycling cost in developed country is, however, not viable, and thereby, huge volume of e-waste is being exported to the developing countries like India, China, Brazil etc., where
