2024年3月4日 · A new method for recovering high-purity gold from discarded electronics is paying back US$50 for every dollar spent, according to Swiss researchers – who found their all-important...

2014年3月7日 · lectronics-technology engineer Josehf Lloyd Murchison claims he has extracted up to $1,600 (£980) worth of gold in three months of collecting junk electronics -- and you can too.

2016年2月4日 · There are two standard methods for extracting gold from electronic scraps: burning off the gold using high temperatures, which is energy intensive, expensive, and releases toxic gases. The second way involves leaching chemicals like a cyanide solution, which is also expensive and toxic, plus the remaining waste cannot be recycled.

2025年1月4日 · A team of researchers led by Cornell University has created a method to extract gold from electronic waste and repurpose it as a catalyst to convert carbon dioxide (CO2), a major greenhouse gas, into useful organic materials.

2025年1月7日 · Led by postdoctoral researcher Amin Zadehnazari, the team has unveiled a major recycling breakthrough: a chemical-free method for extracting most gold from electronic waste, or e-waste, and...

4 天之前 · The Cornell research team, led by Amin Zadehnazari and Alireza Abbaspourrad, synthesised a pair of vinyl-linked covalent organic frameworks (VCOFs) capable of selectively capturing 99.9% of gold from discarded electronics. These frameworks are designed to target gold ions while minimizing the extraction of other metals, such as nickel and copper.

Waste computers and cell phones, solar panels, and other electronic waste are becoming an important source of noble metals alongside mining.

2025年1月2日 · A research team has developed a method for extracting gold from electronics waste, then using the recovered precious metal as a catalyst for converting carbon dioxide (CO2), a greenhouse gas, to ...

2025年1月2日 · Electronics waste is a literal gold mine: It’s estimated that a ton of e-waste contains at least 10 times more gold than a ton of the ore from which gold is extracted. And with an anticipated 80 million metric tons of e-waste by 2030, it’s increasingly important to find ways to recover that precious metal.

2024年4月23日 · Scientists have figured out a way to recycle important metals trapped inside electrical waste. Using textiles, researchers from the Korea Institute of Science and …
