A process for the elimination of non-ferrous metals, for example copper, zinc and lead, as well as arsenic and antimony from roasting residues of pyrites and similar materials, characterized in that a chlorinating volatilization, known per se, of the contents is combined of non-ferrous metals, with gaseous chlorinating agents at temperatures of about 800-1000º c, and a subsequent volatilization reducing the residual content of arsenic and antimony, with gaseous reducing agents at temperatures above 800º c, preferably from 1000 to 1200º c.
