Researchers at Flinders University in Australia have developed a safer and eco-friendly method to extract gold from electronic waste like old computers.
The new technique avoids the use of toxic substances such as cyanide or mercury, reducing environmental harm caused by traditional mining.
Using a common disinfectant and a special material made from sulfur, the team can dissolve and capture gold from waste materials with high purity.
The breakthrough aims to reduce environmental and health risks associated with gold mining, especially in developing countries, and promote recycling of valuable metals from electronic waste.
