“Graphene turns rubbish into gold, literally.”
can be enough for extracting nearly 2 grams of gold. As graphene costs less than $0.10 per gram, this can be very profitable, with gold priced at around $70 per gram.
“This apparent magic is essentially a simple electrochemical process,” Yang Su, co-author of the study, said in a media statement. “Unique interactions between graphene and gold ions drive the process and also yield exceptional selectivity. Only gold is extracted with no other ions or salts.” Su explained that the graphene-based process, with its high extraction capacity and high selectivity, can reclaim close to 100% of gold from electronic waste. This offers an enticing solution for addressing the gold sustainability problem and e-waste challenges.
“Graphene turns rubbish into gold, literally,” said Andre Geim, co-author of the paper and Nobel laureate responsible for the first isolation of graphene. “Not only are our findings promising for making this part of the economy more sustainable, but they also emphasize how different atomically-thin materials can be from their parents, well-known bulk materials.”
