With over 300 tons of gold used in electronics each year, end-of-life electronic equipment offers an important recycling potential for the secondary supply of gold. With gold concentrations reaching 300-350 g/t for mobile phone handsets and 200-250 g/t for computer circuit boards, this “urban mine” is significantly richer than what is available in primary ores. Although miniaturization and thrifting efforts drive down the specific gold input, the booming growth in sales of electronic devices and their inbuilt features to become “smarter and quicker every year” have led to a substantial net increase in gold demand over recent years. Mobile phones and computers are a good example in this context. At the end of their use, these and other electronic
products offer an important recycling potential for the
secondary supply of gold.
