But the highest leaching rate of gold was identified as approximately 92.8 and it was difficult to achieve higher rates by controlling the conditions of temperature time and concentrations of H 2 SO 4 NaCl and NaClO 3. This reveals that the leaching behavior of gold in the chlorination process is the key to improve the gold leaching rate.
