| Abstract: | The Purification of lean impurity elements Pb,Al and As in the electrolytic solution for alkaline leaching of lead-zinc ore was researched.The experimental results indicated that the 82.3% of impurity element Pb in the electrolytic solution could was removed by using Na2S at the optimum conditions of purifying temperature 70℃,purifying time 90 min,aging time 48 h;the 21.1% of impurity element As in the electrolytic solution could was removed by adding 1 g/L ferric sulfate under a constant temperature of 90℃ and mixing for one hour;the 39.9% of impurity element Al in the electrolytic solution could was removed by adding 1.5 g/L sodium silicate under a constant temperature of 90℃ and mixing for one hour. |
