| Abstract: | This paper studies on the technology and the parameter of the production of feed grade zinc oxide from the chemical industry by product sodium hydrosulfite. The approach emphasized the valid channels of the reduction of Pb,Cd and the increase of purity of feed grade zine oxide.The experiment,by using the Mafi forge technique,shown by controlling the quality of zinc sources of the production of Sodium Hydrosulfite and Rongalite the main content of the feed grade zinc oxide could be inereased to 98.3%, while both Pb and Cd decreased to ca.0.0007% respectively. The trade standard of the People's Republic of China of the feed additive zinc oxide was formulated based on this research. |
