Residues, zinc refining flue dust wastewater, mercury-selenium
The hot gases obtained by the roasting of raw zinc concentrate are cooled and cleaned from dust by passing through a spray of dilute sulfuric acid and/or water. This acid and/or water is filtered; the solid residue contains most of the volatile components of the concentrates to be roasted.
