From a global perspective, there are approximately 3 million tons of zinc concentrate or the equivalent of global output 2/5 of the concentrate was put into the international market, in which Japan and South Korea about acceptance of one million tons, Western Europe about of 180 million tons. In recent years, Europe and Japan, zinc ore production declined, while refined zinc production is an upward trend, so these countries and regions increasingly dependent on imports to meet concentrate smelting needs.
In 1986, the country is an importer of zinc oxide, zinc oxide, when the production of 336,000 tons. Imports 117,000 tons zinc oxide, zinc oxide concentrate imported 9,163 tons, 6,245 tons imported timber zinc oxide, zinc oxide export 56,700 tons, 1,200 tons of zinc concentrate exports, exports 173 tons of zinc metal. China's zinc production in that year accounted for only 5% of the world zinc production. Since 1987, China has become an exporter of zinc and lasted until 2003. Chinese zinc industry continues to expand at the same time brought tremendous changes in trade patterns of zinc. 2004 of zinc oxide market has undergone a fundamental change in the amount of annual imports of zinc metal volume of about 500,000 tons, from the world's leading exporter of zinc market re-transformed into the major importing countries, but this time the Chinese zinc industry has and 1986 is quite different. 2004 world production of zinc ingots 10.102 million tons, China's output of 2.519 million tons, accounting for 25% of world zinc production.
The past two years, China's industrial industrial scale zinc oxide and production capacity also rising, mining, dressing, smelting capacity of the average annual growth of more than 10%; but zinc smelting products are still in short supply, the whole of 2005, China's imports of unwrought zinc 62.8 tons, an increase of 35%; first half of 2012, imports of unwrought zinc and 279,000 tons, an increase of 13.4%.
