Research Summary Waste Decontamination The hydrometallurgical leaching of native gold from goldbearing ores or the dissolution of gold metal during the recycling of electronic and precious metal scrap is performed every day using hazardous chemicals such as sodium cyanide or aqua regia.
Nitric acid or forced air oven oxidation can also be used to dissolve iron from the electrowinning cathodes before smelting Gravity concentrates can often contain high grinding steel contents and so their removal using shaking tables or magnets is used before smelting During smelting iron can be oxidized using nitre.
