An interdisciplinary staff of consultants in inexperienced chemistry, engineering and physics at Flinders College in Australia has developed a safer and extra sustainable strategy to extract and recuperate gold from ore and digital waste.
Defined within the paper “Sustainable gold extraction from ore and electronic waste,” in Nature Sustainability, the gold-extraction approach guarantees to scale back ranges of poisonous waste from mining and exhibits that high-purity gold might be recovered from recycling beneficial parts in printed circuit boards in discarded computer systems.
The challenge staff, led by Matthew Flinders Professor Justin Chalker, utilized this built-in methodology for high-yield gold extraction from many sources—even recovering hint gold present in scientific waste streams.
The progress towards safer and extra sustainable gold restoration was demonstrated for digital waste, mixed-metal waste, and ore concentrates.
“The study featured many innovations, including a new and recyclable leaching reagent derived from a compound used to disinfect water,” says Professor of Chemistry Justin Chalker, who leads the Chalker Lab at Flinders College’s Faculty of Science and Engineering.
“The team also developed an entirely new way to make the polymer sorbent, or the material that binds the gold after extraction into water,…
