Abstract

"PROCESSO PARA ELABORAR POEIRAS OU MISTURAS DE POEIRAS". Em um processo para elaborar poeiras ou misturas de poeiras, as quais contêm álcalis e metais pesados, tais como por exemplo, poeiras de aciarias, minérios finos ou poeiras de alto forno, as poeiras são introduzidas sobre ou em um banho de metais líquidos e escórias oxídicas líquidas, são especialmente insufladas ou sopradas. Compostos de metais pesados voláteis, tais como por exemplo, óxidos de zinco e/ou de chumbo são separados da fase gasosa e álcalis são introduzidos nas escórias.
