- Abstract
The removal of arsenic at atmospheric pressure by alkali leaching at atmospheric pressure from black copper slime in NaOH-H2O2 O2 system was studied. The effects of NaOH mass concentration, H2 O2 addition, liquid volume/solid mass, leaching temperature and time on leaching rate of arsenic were examined. The results show that under the optimum conditions, leaching rate of arsenic is 98. 46%. The selective separation was realized, and copper, antimony, bismuth and other valuable metals were enriched in the leaching slag.
