Abstract
There was considered process of recovery of selenium dioxide in calcination-selenide technology of selenium obtaining in metallurgical shop of copper plant of Polar division MMC «Norilsk Nickel». There was established that discharge of selenium in the air occurred as fine dispersed condensation aerosols SeO2, which did not recovery by the apparatus of «dry» and «wet» gas cleaning. The content in aerosols of crystalline phases of sodium selenite, copper and nickel is negligible. During researches there were proposed measures on improvement of hollow scrubber operation and substitution of jet-foaming apparatus for foam scrubber. Outfit of scheme of scrubbing by spray-type absorber-condenser, in which will be realized steam condensing enlargement of aerosols of SeO2, will allow more effectively recover aerosols and transform engineering scrubbing into sanitary one.
