<p>For reprocessing sludges containing heavy metals, in particular sludges from the electroplating industry, it is proposed to mix these with clay and then to fire them to form clinkers. For this purpose, firing temperatures between 750 and 1150 DEG C are selected, it also being possible to admix fluxes in addition to lean clays, in order to ensure the desired vitrification.</p> |
