The metal content of a PCB is typically ten to a hundred times higher than that of conventionally mined ores. 11 It is estimated that recycling one ton of mobile phones could produce on average 130 kg of copper 3.5 kg of silver 0.34 kg of gold and 0.14 kg of Pd. 12 On this basis the global e-waste management market is projected to produce an
· Currently the printed circuit boards (PCB) of waste electrical and electronic equipment (WEEE) are attracting interest among researchers for environmental concern reasons and mainly for their content of precious metals such as gold. Thus this study aims to characterize different types of PCBs from mobile phones in relation to the amount of gold contained to evaluate alternative leaching

How to Extract Gold From Electronics In this Instructable I will show you how to extract gold from computers using products most people have lying around in their homes. The way I extract the gold is relatively straight-forward and pretty easy but the chemicals used are very dangerou
· computers will jump 5 times while from discarded mobile phones will be 18 times higher compared to 2007 level. The printed circuit board is a major constituent of the obsolete and discarded electronic scrap and it accounts for approximately 30 of the total e-scrap generated. It has homogenous mixture of organic material metals and glass fiber.
After you have sorted the circuit board parts pour the water off through the coffee filter and flush with methyl hydrate to clean. Since the methyl hydrate is 99.9 methyl alcohol it cleans and dries the gold flakes better and faster than water water will cling to the gold flakes and give you a false weight.
· Gold Plated Circuit Boards Gold recovery from cleaned gold plated circuit boards is very easy. You can use the gold finger recycling method for gold plated boards. If you want more then burn them. After burning grind them and apply the gold finger recycling method. If you are new and don t know about gold recovery from gold

From a literature review (leaching of gold ores mostly) it was found that there are two research lines. Some authors worked with lower concentrations of thiosulfate and ammonium for a leaching time of 4 hours whereas others worked with higher concentrations of thiosulfate and ammonium and a leaching time of 24 hours (O Malley 2002 Zhang 2004 Xu et al. 2015 Aylmore et al. 2014
