New Way To Recover Gold From E-Waste

Gold From E-Waste

Scientists have discovered a new financially viable and environmentally friendly way to recover and recycle gold from e-waste. Recycling gold from electronic scraps like computer chips and circuits involves processes that are costly and have environmental implications.In this technique, the gold extraction is done under mild conditions, while the solution dissolves gold at the fastest rate ever recorded.

With lower toxicity, cheaper cost and quicker extraction, the team has discovered an approach that could revolutionise the industry and be a veritable gold mine, researchers said. Scientists have discovered a process using a solution - acedic acid combined with very small amounts of an oxidant and another acid - that extracts gold efficiently and effectively without the environmental concerns of current industry practices.

With the new solution, one kg of gold can be extracted using only 100 litres of solution, all of which can be recycled over gain. The overall cost of this solution is only 50 cents a litre.The biggest issue with gold is it is one of the least reactive chemical elements, making it difficult to dissolve, said scientists. World produces more than 50 million tonnes of electronic waste per year and 80 per cent of that winds up in landfills
