  2023313 · Gold can be extracted from gold plating baths, printed circuit boards, and goldsmithing wastes by sodium hypochlorite leaching. However, the leach liquor should be purified to remove other metallic ions and recover the gold from the mixture. While most metals form cations in solutions, gold occurs in anionic complexes. This property makes it …

  GOLD RECOVERY FROM PRINTED CIRCUIT BOARDS OF …

  201891 · The results showed that the content of gold varied from 142 to 700 g/ton. The cyanide-based solution was able to extract 88% of the gold, while sodium and ammonium thiosulfate extracted 70 and 75% of the gold, respectively. The electrowinning tests showed a 94% recovery of the gold present in thiosulfate solutions.
