Gold recovery from ewaste Postconsumer electronic waste contains a large range of valuable elements that can potentially be recycled. An analysis by the UN ewaste coalition reports that 7% of the world's gold reserve may be contained in ewaste and there is 100x more gold in a tonne of smart phones compared to a tonne of gold ore, leading to increasing interest in 'urban mining' to ...
· In this study, a novel way of gold recovery from electronic wastes was developed by means of employing COP180 as a particularly powerful gold adsorbent and using an acidic thiourea solution as an effective and yet mild desorption reagent. At an optimal condition, gold leaching efficiency reached up to 97%. This exceedingly high efficiency with no aiding agents was possible because co .
· Starting around 2007, Ting and his colleagues decided to try using C. violaceum to recover gold from ewaste. The microbe produces an enzyme that converts glycine to hydrogen cyanide, and the cyanide ions in liquid solution bind to gold atoms, grabbing them from solid electronic scrap. The bacterium even cleans up after itself: It later converts unused cyanide to a nontoxic chemical called β ...
