The invention belongs to the field of non-ferrous metallurgy, and provides a selenium removal method for purifying foul acid from copper smelting flue gas. The foul acid is reacted with copper powder to obtain the foul acid after selenium removal. Using the above scheme, the selenite in the foul acid is converted into copper selenide and copper selenite by using the copper powder. The reaction mechanism is simple, the selenium removal effect is good, and for copper smelting enterprises, the raw copper powder is very easy to obtain, and the inactive copper powder can also be directly returned to the copper smelting process, so both the cost of raw materials and the cost of waste treatment are extremely low. . |
