Extraction of Gold from Electronic Waste and Ores
The global gold supply recycled from electronics reached above $7 billion in 2018. The United Nations Environment Program estimates that only 15-20 percent of WEEE is recycled; the rest goes straight into landfills and incinerators. What’s more, the lure of the urban mine has driven growth in the unregulated recovery of metals from WEEE.
