China is a country with extensive resources of tungsten, tungsten reserves ranking first in the world, but this has not yet resource advantages into industrial advantages, tungsten industry in China's current resources, the scale of production, technology and equipment, environmental protection, and research and development capabilities and there exist many problems, Compared with foreign enterprises gap obvious that these factors constrained the tungsten industry to develop and grow.
First of all, ensure that resources are gradually extent shortage trend. According to China Tungsten Industry Association, the China Tungsten forefront of the world's reserves, is one of the few advantages of minerals, and has widely distributed, the relative concentration of resources and so on. However, technical, economic conditions, the use of currently available resources of wolframite tungsten ore resources only 30% of the total. In accordance with the existing production and the increase in domestic consumption, coupled with the low recovery rate of mining Luancaijianwa phenomenon has not been radical, the existing reserves of tungsten mining static guarantee only 12 years, and tungsten resources for a shorter time. If no increase in resources exploration, China's tungsten ore resource advantages will soon be at a disadvantage.
Secondly, tungsten products scale is too large, concentrated production was low. Refined products to APT for example, the 36 enterprises has reached capacity 108,000 tons, but the actual size of more than 3,000 tons in the production of only 17. 2003, the production of Ammonium Paratungstate 46,500 tons, capacity utilization is only 43%. Processing cemented carbide products as an example, the capacity of 160 enterprises 21,000 tons, with the exception of two production enterprises output reached 2,500 tons and above, the majority of enterprises output was only several tons. 2003, the National carbide production was 1.24 million tons, capacity utilization is only 59%.
Third, the overall level of technology and equipment is not high. Most of the current domestic smelting enterprises relatively backward technology and equipment, mainly fine performance in the production of tungsten powder, ultrafine tungsten powder and tungsten carbide powder in the process, because purification technology, equipment and control issues, and product quality instability; some domestic enterprises processing technology and equipment also 20 in the 1980s and 1990s, resulting in fewer products of different specifications, the lack of excellent performance tungsten materials, processed products less deep, and so on.
Fourth, the relatively low level of research and development. Compared with advanced countries, China's lack of a group to support and promote the optimization and upgrading of industrial structure of large enterprises, the lack of a group with independent intellectual property rights, prominent main industries of large corporations. In the development and utilization of resources, Ultra compounds, high-performance alloy, the new field of application development, the large disparities.
Fifth, the ecological balance is very grim. Because tungsten ore Luancaijianwa, blind production have not fundamentally resolved, environmental pollution, ecological destruction, and soil erosion is very serious. According to incomplete statistics, the domestic enterprises tungsten ore was discharged directly into rivers each year of solid waste to 2.2 million cubic meters.
