Abstract
A process for treating smoke from steel plants coming from blast furnaces, electric furnaces, converters and cupola furnaces. The process of the invention consists first of all in separating, when hot, the iron and iron oxide dust from the smoke by contact with solid particles, then in cooling this smoke to solidify the non-ferrous metal vapors which they contain, then finally in separating the solidified non-ferrous metals. It is possible to recover for a smaller cost, on the one hand, the iron and iron oxide dust and, on the other hand, the non-ferrous metals in solid form. Heat may also be recovered.
