Extracting Gold from E-Waste - AZoCleantech
2017-10-26 This extraction process involves the chemical reaction between the pulverized e-waste and sodium cyanide, which produces a soluble gold cyanide solution that allows for easier extraction of the precious metal 3. While useful, gold cyanidation remains a controversial technique that is prohibited in several countries around the world.
