Zhengzhou Comprehensive The scientists have found a new type of tungsten ore in the rock and mineral identification process. The study determined that the ore containing rare earths, tungsten ore elements in the form of ion adsorption occurs in the main carrier mineral containing barium psilomelane .

After identification, the ore grade of the total rare earth oxide 0.23%, W and rare earth elements are enriched in barium-containing Eu psilomelane , and the uniform distribution. Which , Eu2O3 content of between 0.34% ~ 0.47%, W2O3 content of between 3.2% to 4.2 %.

Deposit of rare earth industry mainly endogenous Bastnaesite and monazite ores , exogenous ion adsorption type ( weathering crust ) and sedimentary placer ( monazite type ) ore. Zhengzhou integrated with the newly discovered rare earth tungsten ore mainly occurs in sandstone fracture zone in the case of table generation due to the detailed causes of further study. The researchers said the mine 's ore-forming elements specific combinations and unique mode of occurrence was first discovered in the country is worthy of further study.

According to the Principal revealed that this type of tungsten ore reserves larger prospecting better. The discovery , for improving the utilization of the value of the tungsten ore is significant. This is a major contribution to the Mineral Exploration Zhengzhou comprehensive appraisal made ​​by the rock .

Tungsten market downturn continued atmosphere of tungsten concentrate turnover continued stalemate, despite holding the goods will ship cheap low, dragged down by weak demand , the current market price of the mainstream gradually approaching the low price range , the recent mainstream smooth tungsten market or continue to supplemented by a slight decrease .

Macro level, the spot exchange rate of RMB to new lows, the depreciation of more than 3% since the beginning ; MIIT: serious excess capacity of industry mergers and acquisitions windows began to appear ; April HSBC China PMI data showed a slight improvement in the economy .

Tungsten market downturn continued atmosphere of tungsten concentrate prices dropping slightly again , now close to cost price , focusing on 105,000 / ton. Earnings hold stocks and smelters family are very low , many businesses temporarily offer , not shipped , the market volume was light, wait and see mood strong . Of course , there are some cargo operators because of funding constraints, eager to cash in and sell cheap , so the market presence of a small amount of low turnover .

However , buyers are mostly bargain hunters follow the principles of the market now active inquiry , but the inquiry and more low , buyers and sellers on the price seesaw .

Market analysts believe that the current supply an adequate supply of tungsten concentrate , inquiries also have, but mixed views on the outlook and the two sides deadlocked transactions . Purchaser believes the short-term market was weak and suppress tungsten concentrate inquiry , the Vendor promising tungsten market and offer strong long-term market is expected to short-term absence of external force , which saw the phenomenon is difficult to break , next week, or hard tungsten concentrate a significant improvement in turnover .

Tungsten is extremely scarce and irreplaceable strategic resource , but also the national economy and national defense irreplaceable foundation of modern materials and strategic resources , manufacturing tungsten carbide known as "dental industry ," Carbide widely in the areas of military, aerospace, machinery processing , metallurgy, oil drilling , mining tools, electronic communications, construction , etc., is the key material tungsten lighting , electronics and other industries. In these applications, has not yet found a direct substitute for tungsten.

Currently, only the world's total proven reserves of tungsten 2.898 million tons , is extremely scarce resources , more than 20 kinds of the world's known tungsten minerals , industrial value only scheelite and wolframite are two, wolframite are quality tungsten ore, scheelite are refractory ores . China 's tungsten resources abundant , accounting for nearly 70% of the world 's proven reserves of tungsten mineral resources , ranking first in the world .

2010-2013 , equivalent to the amount of tungsten concentrate production increased year by year , and reached its highest level in 2013 , tungsten concentrate production was 138,000 tons .

Through the analysis of primary tungsten and "Twelfth Five Year Plan" according to the analysis of waste tungsten tungsten industry, we assume that the future of native producers of tungsten in tungsten concentrate production quota increase of 1% per year , the 2017 Chinese tungsten concentrate equivalent to the amount of production will reach 143,600 tons .

2014-2017 Chinese tungsten ore market analysis research has been mentioned in the report , domestic demand for tungsten basically showing steady growth in the state . Although the impact of the financial crisis is not over , the European sovereign debt crisis is still spreading and so the constraint of global economic development, but the trend of global economic growth will continue, tungsten demand will continue to grow in 2015 , total global demand may up to 83000t, with an average annual growth rate of 4%.
