Zusammenfassung: | The invention relates to a method for recovering hydrochloric acid in anti-molten iron during an indium extraction process, which comprises the following steps of distillation and condensation; a condensate liquid is hydrochloric acid which is obtained through recovery, then is returned to a production line for re-usage; the rest mother liquor through distillation is a ferric trichloride solution, the rest mother liquor is subjected to continuous distillation to obtain a concentrate, and the concentrate is used for producing the ferric trichloride product. The method has the advantages of simple process, easy control of the process and high recovery rate, the problems of environment pollution and resource waste caused by the anti-molten iron processed by a conventional method in the indium extraction process can be solved, the hydrochloric acid recovery rate is increased, and the resource utilization rate is increased. |
