    Mar 01, 2009· In the case of gold, this fact might be responsible for the increase in the gold volatilization from mineral since in the presence of iron chloride, a binary complex AuCl 3.FeCl 3 would be formed. Then, the following reactions for gold extraction might be proposed Fe 2 O 3 + 3 Cl 2 (g) → Fe 2 Cl 6 (g) + 3 2 O 2 Fe 2 Cl 6 (g) + Au + 3 2 Cl

  • Gold extraction by chlorination using a pyrometallurgical

    Results indicate that gold extraction is favored by increasing, both, the temperature and the reaction time. The best recovery values were of 98.23% at 873 K and 3600 s and of 98.73% at 873 K and 5400 s, with very low attack of the matrix containing the metal. The powder of pure gold was not chlorinated at this temperature level.
