Sustainable gold extraction from ore and electronic waste
Gold plays an essential role in the global economy and has wide applications in various industrial technologies. Currently, the gold supply relies heavily on mining processes that employ toxic substances such as cyanide salts and mercury metal, leading to substantial environmental pollution. Gold extraction approaches that do not rely on cyanide and mercury are needed to improve the overall sustainability of gold production. Here we develop an a…
Ferritin protein can be used to separate critical metals from electronic waste
When phones or computers are recycled, small amounts of important materials get discarded. Those minute amounts of cobalt, nickel and lithium add up quickly, and separating and recovering these "critical materials" for reuse is a dirty, energy intensive job.
Motherboard motherload: recover gold from electronic waste
Electronic waste from discarded computers is a growing challenge. Credit: Flinders University Researchers have developed a “low-cost, sustainable, simple and safe” approach to extract gold from ore, mixed metal waste and electronic waste. The demand for gold is rising. Highly valued by investors and as a critical component of electronics, medicines, aerospace technology and other products, experts say we must develop safer and more versatile met…
Striking Gold: E-Waste Mining Uncovers Wealth While Benefiting the
An interdisciplinary team at Flinders University in Australia has unveiled a groundbreaking method for extracting gold from ore and electronic waste that addresses environmental and health concerns associated with traditional mining practices. This innovative approach could redefine the gold recovery landscape by minimizing the environmental footprint often associated with conventional extraction routes that rely heavily on toxic chemicals like …
Gold is a valuable raw material for many industries, but its sources are limited. Engineers and chemists have now developed a new technique to extract high purity gold from ore and electric scrap. The method uses non-toxic chemicals, which can be recycled for the most part. This gold recovery technology is therefore more sustainable and safer than conventional methods and could [...] The post New method for gold recycling from electric scrap fir…
