From a global perspective, every year there are about 3 million tons of zinc concentrate or the equivalent of the global total output 2 / 5 of the concentrate was distributed to international markets, including Japan and South Korea accepted about 1 million tons, about Western Europe To 1.8 million tons. In recent years, Europe and Japan zinc ore production decreased, while refined zinc production showed a growth momentum, these countries and regions increasingly dependent on imports of concentrate to meet the demand for smelting.
        In 1986, China is an importer of zinc, Xinding production was 336,000 tons. Xinding imports of 117,000 tons, imports of 9,163 tons of zinc concentrate, imported 6,245 tons of zinc material, Xinding export 56,700 tons, export 1,200 tons of zinc concentrate, exports 173 tons of zinc material. That China's zinc production of the world's zinc production to 5%. From 1987 onwards, our country's exports of zinc and has been maintained up to 2003. China's zinc industry growing at the same time brought the huge zinc and trade pattern changes. In 2004, China's zinc market has changed radically, the year of zinc metal imports about 500,000 tons, the world zinc market from the major exporting countries to change the main importing countries, at a time when the zinc industry has with China 1986. 2004 world production Xinding 10.102 million tons, China's output of 2.519 million tons, the world's total zinc output of 25%.
        The past two years, China's zinc industry industrial scale and production capacity are also constantly improving, mining, mineral processing, smelting capacity of the average annual growth of more than 10%, but zinc smelting products are still in short supply, the year 2005, China's imports of unwrought zinc rolling 628,000 Tons, an increase of 35 percent of the first half of 2006, imports of unwrought rolling 279,000 tons of zinc, an increase of 13.4%
