Patent

CA 2223044

Iron-rich material waste products, such as electric arc furnace dust, are formed with an organic binder into discrete shapes, such as briquettes and/or other solid shapes. The shapes can then be used in iron and steel making processes and the iron and heavy metal values in the waste product recovered.

Cette invention concerne la transformation, à l'aide d'un liant organique, de déchets de matériaux riches en fer, tel que les poussières d'un four à arc, en formes discrètes, tel que des briquettes et/ou d'autres formes solides. Ces formes peuvent ensuite être utilisées dans des processus de fabrication du fer et de l'acier, le fer et les métaux lourds contenus dans les déchets pouvant être récupérés.
