PROCESSO PARA DESTOXIFICAR REFUGOS DE USINAS DE ACO QUE CONTEM OXIDOS DE FERRO E METAIS TOXICOS |
| 摘要 |
<p>A technique for rendering toxic metals (chromium, lead, cadmium and arsenic) contained in steel plant furnace dust innocuous and suitable for burial with minimal adverse environmental impact. Pelletized iron oxide containing dust is introduced into a rotary hearth furnace under a reducing atmosphere in excess of 600 DEG C. The higher iron oxides are reduced to FeO which in turn complexes with the toxic metals to form relatively benign products.</p> |
