| Abstract: | Aluminum recovery experiments are made by using sludge from an alumihum pTant as raw materials and adopting the hydrochloric acid reeovery method. The effects of hydrochloric acid amount used, reaction temperature, reaction time and aging time on aluminum dissolution are studied. The results show that aluminum dissolution rate reaches 94% - 96% when 20.000 g sludge is dissolved by 12 mL （1＋2） hydrochloric acid at 75-80 ℃ for 25 rain and then aged for 80 min. |
