| Abstract: |
| In industrial-scale experiment, zinc sulfide concentrate was roasted in fluidized bed furnace in low oxidizing atmospheres and temperature, the waste gas was oxidized sufficiently after second combustion, so As and S entranced into waste gas completely and recovered after dust collecting. The results show that arsenic slag is purified to 98% in the third combustion, and the recovery of As2O3 is more than 98%. The arsenic slag is cycling used by getting back to dosing process, the waste gas is used to produce acid after de-arsenic treatment. The whole productive process is enclosed totally and automatically assembly line work. |
