| Abstract: |
| The behavior of arsenic and hazards of arsenic in zinc electrowinning and acid making, and arsenic removal mechanism and treatment for leaching solution and waste acid by ferric salt flocculence process were analyzed in detail. The disadvantages of existing waste acid treating process were analyzed. The future trend to treat waste acid is reprocessed. Zinc hydrometallurgy process should be impromoved to avoid the model of treatment to fix pollution. |
