Abstract

L'invention concerne un procédé pour le traitement de poussières et résidus métallifères de l'industrie métallurgique. Le procédé est caractérisé en ce que les résidus à traiter et d'éventuels additifs sont mis à l'état de boue dans l'eau ou dans une boue acide de décapage, en ce que le pH de la boue est réglé si nécessaire à 7 pour provoquer la précipitation des metaux lourds dans la boue, en ce que l'on sépare l'eau de la boue, et en ce que l'on amène le produit à une forme fragmentaire. Application notamment au traitement des poussières et résidus métallifères de l'industrie de l'acier affiné.The invention relates to a process for the treatment of dust and metal residues from the metallurgical industry. The process is characterized in that the residues to be treated and any additives are put in the form of sludge in water or in an acid pickling slurry, in that the pH of the sludge is adjusted if necessary to 7 to cause the heavy metals to precipitate in the mud, by separating the water from the mud, and bringing the product to a fragmentary form. Application in particular to the treatment of dust and metalliferous residues from the refined steel industry.
