Abstract: The consumption structure of zinc products from 1990 to 2004 in China is analyzed, for which the weighted averaging method is given to calculate the average service life of zine products. The result indicates that the average service life of the zinc products in China increased year by year in recent years on the whole because of the greatly increasing output of galvanized products and copper products. The calculation reveals that the depreciation/recovery period of the zinc products in China is 20 years. Thus, a data foundation is offered to calculate the cyclic consumption of zinc and predict the developmental trend of zinc products.
