<p>In a process for processing waste incineration residues, such as, e.g., waste incineration slags, in which the slags are subjected to a reduction process while separating metals, the solid waste incineration residues are introduced into a steelworks slag bath in amounts ranging from 15 to 45 % by weight, based on the overall quantity, that the heavy metals or heavy metal compounds, such as, e.g., Zn, Pb, Cd or Hg chlorides, evaporating during melting of the waste incineration residues or slag are drawn off and the liquid bath is reduced by aid of carbon carriers and under the formation of an iron bath, whereupon the slag phase depleted from metals is granulated and used as a mixed cement component.</p> |
