Abstract
Features of chlorine and fluorine precipitation from middlings of zinc production are considered; in particular the behavior of these components is studied in experimental conditions at Waelz-process with calcium oxide. It is found out that degree of chlorine and fluorine volatilization decrease to 15% at the content of calcium oxide in charge not less than 20%. It allows in a combination to water washing removing to 97% of chlorine and 85% of fluorine from Waelz-fume with transfer of their considerable part in clinker.
