According to this article, recovering noble metals from waste electrical electronic equipment (WEEE) will provide an additional income within the disposal process of end-of-life electronic devices. Generally, the recycling process starts with the manual dismantling of different devices and sorting the subdivided products into useful and hazardous materials. Computer PCBs were manually dismantled to obtain the easy-to-remove components of the board; namely, the integrated circuits and the processors. These were about 13% weight of the board and 0.1% weight of the whole WEEE sample and contained about 91% of the gold present in the whole board with an average concentration of 2400 _g/g.
