A Brief Summary of Zinc Oxide Processing Methods

2017-6-19  The gases at the outlet of the kiln are mixed with air to re-oxidize the zinc vapor into solid zinc oxide while CO is converted to CO 2. Gases are cooled by adding water and zinc oxide produced is collected in bag houses. This zinc oxide can be used as feed for zinc smelters.

Zinc Oxide Learn About Zinc Oxide ZnO - GHC Limited

In the production of French Process zinc oxide, zinc is melted, then vaporized and drawn into an oxidation chamber. Controlled conditions at the oxidation stage produce the particle size conforming to the individual grades manufactured. When cooled, the zinc oxide is collected, sampled, and analyzed to ensure conformity to grade specifications.
