| Abstract: | Active zinc oxide is an important chemical additive. A process for the production of active zinc oxide was explored using the primary cleaning calamine powder as raw materials. The calamine powder was firstly dissolved in sulfuric acid followed by filtering to isolate the insoluble substance. Both oxidation method and substitution method can be used to remove the impurities contained in the aqueous solution. After that, zinc carbonate was formed and precipitated by addition of low-cost ammonia carbonate. Finally, active zinc oxide was prepared by incinerating the filtered zinc carbonate. |
