Abstract

Procedimiento de valoración del plomo y del cinc contenidos en los lodos de depuración de los gases de hornos altos, caracterizado porque consiste en someter dichos lodos a una clasificación granulométrica hasta un valor comprendido entre aproximadamente 10 y aproximadamente 50 micrómetros, de manera que se concentran el plomo y el cinc contenidos especialmente en los finos, y en recuperar la fracción cuya granulometría es inferior a este valor comprendido entre 10 y 50 micrómetros, mientras que la otra fracción puede ser re circulada hacia los hornos altos.
