METHOD AND APPARATUS FOR THE ELIMINATION OF ZINC FROM RECOVERED STEEL DUST |
| abstract |
Method and apparatus for removing metals and zinc-type compounds from dust from iron processing furnaces before recycling. The dust is collected and concentrated by wet process. They are subjected to a preferential spraying which results in a clear difference in particle size of the components of the zinc type and of the components containing iron. The zinc-like components are then removed by wet vacuum classification, and the iron-containing components are recycled. The invention applies to the treatment before recycling of dust from blast furnaces, converters or electric furnaces. |
