Recovery of zinc from iron-making or steel-refining furnace dust |
| 摘要 |
The zinc-containing dust from an iron-making (blast) furnace or a steel-refining (e.g. converter) furnace is recovered and extracted with water saturated with carbon dioxide to solubilize the zinc. The zinc solubilized in the CO2-saturated water is then precipitated by the elimination of carbon dioxide therefrom.
