· A.4 and the final gold recovery rates are shown in Fig. 4. As leaching of copper as aforementioned there was only a little gold recovered without the pyrolysis pretreatment of waste PCBs. The final gold recovery rates were approximately 69 and 80 when the waste PCBs were pretreated by conventional and microwave pyrolysis respectively.
· 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.

Jul 01 2017 · The printed circuit board represents the most valuable part of e-waste accounting for over 40 of the total e-waste metal value (Golev et al. 2016). BullionStreet (2012) summarized that 320 t of gold and 7500 t of silver is consumed by the electronic industry every year and urban mining of e-waste could generate 21 billion each year.
· Computers and other electronic devices contain gold and other precious metals in their circuit boards. As consumers upgrade their electronic gadgets the precious metals remain trapped in piles of waste. There’s about 0.2 grams (0.007 ounces) of gold in a typical mobile phone handset.

· Abstract. Due to the supply gap towards increasing demand as well as loss of precious metals by illegal recycling present research reports application-oriented processes developed at CSIR-NML India to recover precious metals from small components of e-waste containing 0.1–0.8 Ag 0.03–0.9 Au 0.01–0.02 Pd 0.0003–0.0005 Pt and related effluent.
The recovery of base and precious metals from e-waste can be classified into three types hydrometallurgical (chemical) pyrometallurgical (thermal) and biometallurgical (biological) (Hong and Valix 2014 Tuncuk et al. 2012) ().Physical methods have gained popularity in e-waste recycling as a pre-treatment strategy.
· Introduction to Electronics (E-Waste) Recycling. Electronics waste commonly known as e-scrap or e-waste is the trash we generate from surplus broken and obsolete electronic devices. Electronics contains various toxic and hazardous chemicals and materials that are released into the environment if we do not dispose of them properly.
