Process for producing a concentrate enrichment of metals or oxides thereof from filter dusts by expelling them from the filter dusts in their vapour form and thus collecting them in concentrated form
Process for producing a concentrate enrichment of metals or oxides thereof from filter dusts by expelling them from the filter dusts in their vapour form and thus collecting them in concentrated form
According to the invention, a production process is described which transfers readily volatile metals and oxides thereof, which are contained in certain filter dusts at relatively low amounts, from such filter dusts to enriched concentrates.
