摘要：
A study is conducted to determine optimum conditions for the chlorination of gold in decopperized anode slime with chlorine gas in aqueous medium by the Taguchi experimental design method. The effect of parameters such as reaction temperature, reaction period, stirring speed and solid-liquid ratio was sought. The optimum conditions were found to be reaction temperature 60 degrees C, reaction period 4500 s, stirring speed 600 min(-1) and solid-liquid ratio 0.1 g ml(-1). The experimental results showed that, under optimal leaching conditions, the extraction of gold could be over 99%, (C) 1999 Elsevier Science B.V. All rights reserved.
