Scalable and selective gold recovery from end-of-life electronics
2024年2月8日 · Selective recovery of gold from electronic waste using mild reagents is a challenge. Now a photocatalytic technology is reported to enable highly selective gold dissolution through solvent...
Non-toxic technology extracts more gold from ore - Phys.org
2021年10月1日 · Called electrodeposition-redox replacement (EDRR), the new process combines the best of two common methods for extracting leached gold: electrolysis, which uses electric currents to...
New method safely extracts gold, platinum, and other metals …
2024年4月2日 · A new method safely extracts valuable metals locked up in discarded electronics and low-grade ore using dramatically less energy and fewer chemical materials than current methods, report University of Illinois Urbana-Champaign researchers in the journal Nature Chemical Engineering.
Extracting Pure Gold: Turning Electronic Waste Into Treasure
2024年4月23日 · A fibrous adsorbent selectively recovers high-purity gold from waste. Dramatically reduces the cost and time of the recovery process and enables material to be mass-produced and repeatedly recycled. Korea relies on imports for most of its metal resources, and in recent years, due to resource depl
High-efficiency gold recovery by additive-induced ... - Nature
2023年3月9日 · Here we report an additive-induced gold recovery paradigm based on precisely controlling the reciprocal transformation and instantaneous assembly of the second-sphere coordinated adducts formed...
From Trash To Treasure: New Method Turns Electronic Waste Into Gold
2024年3月10日 · Now, a group led by ETH Professor Mezzenga has come up with a very efficient, cost-effective, and above all far more sustainable method: with a sponge made from a protein matrix, the researchers have successfully extracted gold from electronic waste.
'Exceptional' new tech sees 63% rise in gold recovery at Fulcrum ...
1 天前 · Fulcrum Metals has reported an exceptional increase in its rate of gold recovery from tailings at its Sylvanite project, as it announced the initial results of its testing of Extrakt Process Solutions's processing technology today.
Advances in Hydrometallurgical Gold Recovery through …
2024年6月13日 · This review paper covers various gold recovery techniques, including the Merrill–Crowe process, adsorption, ion exchange, solvent extraction, and emerging novel approaches that utilize ionic liquids and deep eutectic solvents.
Ausome: Non-Toxic Technology Extracts More Gold From Ore
2021年10月13日 · Called electrodeposition-redox replacement (EDRR), the new process combines the best of two common methods for extracting leached gold: electrolysis, which uses electric currents to reduce gold or other metals present in the leaching solution, and cementation, which adds particles of other metals to the solution to react with the gold.
New technology dramatically increases the recovery rate of …
2022年5月17日 · By introducing functional groups that react only with gold ions in the multi-layered internal structure, gold that has passed through the polymeric shell could be stably recovered even with the...
