China's tungsten mining production
After several years of development, China's tungsten mining expanding production scale, technology development capability, market competitiveness has reached a certain level, to the needs of users at home and abroad the production of various tungsten minerals, has made great achievements. In 2006, China's tungsten industry sales income 311 million yuan, sales profit of 6.4 billion yuan, an increase of 7% over 2005. 91 major companies nationwide sales of tungsten carbide plate industry accounted for 63.0%, compared with 2005 growth of 20 percent, including mining, smelting, tungsten carbide, tungsten metal and tungsten iron enterprise sales revenue increased by 22.4%, 20.5%, 16.5 %, 11.7% and 7.4%. 2006 Chinese exports of tungsten 31,710.45 tons, only a 1.8% increase over 2005, an increase of 10.7 percentage points mitigation; exports of 1.09 billion U.S. dollars, an increase of 36.3% over 2005. Imports 7,890.9 tons, an increase of 71.5% over 2005; imports amounted to $ 202 million, an increase of 108.2% over 2005. Net export volume of 23,819.6 tons, 10.3 percent less than in 2005; net exports of $ 888 million, up 26% over 2005. 2006 exports of tungsten equivalent to one ton in 2002, 2003, 4 tons in 2004, 3 tons, 1.3 tons in 2005. First half of 2007, China's tungsten industry production and operation showing a steady and rapid development momentum. 2007 1-6 months, the national output of 40,309 tons of tungsten concentrate (equivalent WO365% volume, the same below), an increase of 18.65% over the previous year. January to June 2007, total export volume of 15,343.8 tons of tungsten metal products, compared with 2006 growth of 8% over the same period, exports 535 million U.S. dollars, an increase of 91.7%. Total imports of tungsten products (including concentrates) metal content of 3430.2 tons, and imports $ 85,335,000, respectively, over the same period in 2006, an increase of 87.5% and 121.9%. Export Carbide 1245.6 tons, a growth of 17.06 percent over the same period, exports $ 479,747,700, down 4.52%, the average export price of $ 385,153.9 / ton, down 18.4%. Chinese tungsten ore resources are monopolized, but did not get monopoly profits. The reason is that Chinese exports of tungsten product structure is irrational, excessive exports, low prices. Primary products with low added value export-oriented, is currently China Tungsten Industry Foreign Trade fatal weakness. With the development of the market, China's tungsten industry gradually complete product varieties, the market structure and the industrial layout slowly norms, tungsten products prices also rose more than two years after the basic stabilized. After 2008, industry consolidation may be accelerated, and this process also pregnant with greater investment opportunities.
