“…We also present on this figure a vapor pressure threshold of 10 −6 atm above which volatilization typically becomes significant based on previous work. [47] According to this criterion, significant volatilization of Zn and Pb starts above 460 and 610 °C, respectively. The evolution of the phase assemblage as a function of temperature is presented in Figure 2.…”

becoming obsolete, especially in electronic devices. In fact, these types of valuable metal concentrations are such that electronic wastes can nowadays be considered as urban mines that need to be exploited. Urban mining is a concept that is emerging in our modern society. According to the United Nations Environment Programme (UNEP), around 20-50 million metric tons of waste electrical and electronic equipment (WEEE) are generated worldwide each year from which approximately 8.9 million metric tons are collected and recycled (about 20%) whereas 1.7 million metric tons are dumped into landfill and incinerated in different countries. [1][2][3][4][5] Direct combustion and landfill are considered the worst handling techniques of WEEE but are still common practices in countries that have no effective regulations or lack of necessary facilities for waste management. [6][7][8] Waste printed circuit boards (WPCBs) are basic non-conductive structures on which different electronic components are layed and electrically connected via conductive materials. As can be seen from Table 1, a standard WPCB consists mostly of:
