2020-10-20 Chemicals used to extract gold from electronics. What chemicals do I need to extract gold from electronics? Nitric acid was used for the extraction of gold. Place radio components in a glass jar, fill it with nitric acid and heated. But directly heating isn’t suggested. Take the bowl with water and put on
In order to extract gold from electronic waste, first, unwanted elements must be removed from the combination. Thus, copper, silver, and selenium were omitted from waste sludge using hydrometeorology method (acidic leaching). In this research, as the aim is analyzing the extraction of gold, to achieve the waste containing gold, all the three
The present disclosure satisfies the aforementioned need by providing a method for recovery of gold from electronic waste and extraction of Au from minerals, ores and sands. The method includes crushing the gold containing material, such as electronic waste material or the gold containing minerals, ores and sands to obtain a particulate material.
