There are two current industry standards for removing gold from electronic scraps the first is pyrometallurgy which burns the gold off using high temperatures
A bacterium called cviolaceum is used for separation of gold from electronic waste and based on experiments it was observed to dissolve fourteen percent of gold from 10 mg of dicyanourate these organisms can separate metals from electronic waste after they are broken to small pieces through process like shredding
Nov 13 2019 electronic waste ewaste is a growing problem but it also presents an opportunity to recycling plants looking for new ways to grow ewaste is full of reusable metals gold silver and copper just to name a few using our system of metal recovery recycling centres can process ewaste to recover the valuable metals inside and sell them to refiners giving them an added stream of revenue metals
Pyrometallurgical treatment melting oven melting unit aim to remove lead and tin from precious metals it can reach 2000 0 c system designed for the recovery and refining of precious metals also system widely uses treatment of gold and silver from ashes of jewellery scraps
Any gold which was trapped in the solution has now be come a brown precipitate at the bottom of your beaker retest with stannous chloride if your reaction still turns purple you need to add more stumpout it will take appox 10 hours for the gold to competely settle the solution should be clear at this point

Feb 20 2020 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
Mar 28 2017 mix a refining solution although you have recovered the gold from the electronics scrap it may not be pure gold it may be 12k or 18k gold so now we will refine it to be pure 24k fine gold take a second beaker and pour it half full of aqua regina

For most largeescrap recyclers the most common solution of precious metalrecoveryis sellingescrap materials to one of the few large smelters in the world and the smelters apply pyrometallurgical method burning everything in furnace toprocesstheseescraps and give the recyclers credits after many discounts and management fee charges
Oct 10 2019 therecoveryof theseprecious metalsis no small issue while a modern recycling facility can recover as much as 95 ofgold in developing countries the crude dismantling processes employed may recover only 50 of this precious metal also if done incorrectly therecovery processcan expose workers to a wide range of hazardous substances
