"Black chain," large-scale invasion of China Rare Earth Industry

China's largest rare earth production base in Baotou City, Inner Mongolia Autonomous Region , the customs authorities after nearly a year of investigation monitoring, together with the recent detection of a rare earth smuggling cases , involving more than 130 tons of rare earth products , the value of the total amount involved in the case and reached more than 1,400 yuan of tax evasion .

Survey shows that from December 2011 , Baotou , a private enterprise in the case of Vietnam KAD foresee the company you want to buy rare earth products smuggled out of the country , still do not issue VAT invoice prices reached a sale and purchase agreement with the latter , has the 6 batches of rare earth products illegally sold to KAD companies.

And this phenomenon of illegal production and sale of rare earth products in the current Chinese rare earth industry is not uncommon , Qingdao and Shenzhen customs authorities cracked several times in recent years, the amount of rare earth billion on major smuggling .

"' black chain ' is the invasion of China 's rare earth industry . " Baotou Steel Rare Earth ( Group ) Hi-tech Co., Ltd. , general manager Zhang and many other rare earth enterprises generally believe that the person in charge , illegal mining, processing and sale of rare earth export activity is rampant , affecting the healthy development of China 's rare earth industry a cancer in 2012, since the rare earth prices continued to slump, a lot of impact "Black RE " The market is a major reason.

Located in Baotou, Inner Mongolia 's Bayan Obo polymetallic Ore , is the world's most resource -rich light rare earth region . Before this often someone stole mine, mining companies built around a two- meter-high fence, dug three meters wide and two meters deep in the trenches , and the mining area patrolled 24 hours , but even so , the phenomenon is still stealing mine could not ban .

In the southern provinces of Jiangxi , rare earth mines scattered, private dug illegal mining of rare earth ore processing and sale of rare earth products, the phenomenon is repeatedly played without a break.

" In 2012, the Southern ionic rare earth ore mining production was 13,400 tons mandatory plan , but the statistical analysis of the data shows that in 2012 the South at least mine produced 37,000 tons , nearly 70 percent of unknown origin . " Secretary-General of China Rare Earth Industry Association马荣璋said.

Ministry of Industry and Information Technology , an official at the previous meeting held on to say that the recent Chinese illegal, illegal mining and production is still relatively rare phenomenon seriously , in 2012 the country is expected to have illegal production over 40,000 tons , 5 illegal smelting separation products thousand tons .

"Black RE " a lot of flooding the market, smuggling of rare earth elements to provide a steady stream of supply. Meanwhile, some shortcomings Chinese rare earth export quota management system still exists and Chinese rare earth export tariff , the development of product catalog to keep up with the reality of the industry , but also led to rampant smuggling of rare earth .

Insiders pointed out that there are 17 kinds of rare earth elements , and uses very different characters , but after half a century of development , China has been able to produce more than 400 categories, more than 1000 kinds of specifications of rare earth products . However, the current rare earth export tariff was only fifty or sixty , and some products and export tariff disjointed , catalog management is not fine , insufficient detection capability , exacerbating the regulatory challenges .

In fact , for the rare black industry chain , the Chinese government in recent years has been to take remediation action. 2011 and 2012 , the Ministry of Industry and Information Technology jointly with relevant departments , the order of twice the rare earth industry to carry out special rectification action. In order to further regulate rare earth production and sales order, this year on August 15 to November 15 , the Ministry of Industry and Information Technology eight departments have jointly implemented a new round of combat illegal production and sale of rare earth special action .

"In the past two years, have been punished exploration and mining of rare earth behavior from more than 600 , destroyed 14 illegal mining sites , ordered about 90 mines and smelters of rare earth separation , rectification. " Industry and Information Technology Ministry official said.

These special rectification activities really made ​​great achievements , but some industry insiders said , is not enough long-lasting effect . China rare earth distribution area is very wide, often special events over, criminals began to perk up . Some illegal rare earth mining, smelting and separation plant also " limelight " after the resurgence .

马荣璋and other experts believe that the current illegal Chinese rare earth production enterprises that difficult, imperfect laws and regulations , enforcement is difficult, between the central and local governments , has not yet formed between sectors and regions reasons unified and efficient law enforcement system, and have restricted the remediation and combat effectiveness of the special action .

Meanwhile , profits also increased the temptation for the rare earth industry chain black combat difficulty. Currently produced in the northern mining rare earth ore at 05,000 yuan per tonne of resource tax to 1.4 million range , rare earth mineral resources tax per ton mine in southern 06,000 yuan to 36,000 yuan range, resource tax plus other taxes already the price per tonne of ore accounted for more than 50% , do not need to pay any potential illegal digging of private taxes , big profit margins .

"A lot of 'black Rare ' big impact on law-abiding businesses . "President Cui Jiangxi Rare Earth Industry Association , said the source sent to southern Jiangxi heavy rare earth mine , for example, rare earth ore per ton in the current 160,000 to 170,000 yuan per ton processing cost 40,000 to 50,000 yuan per tons environmental costs of 15,000 yuan to 20,000 yuan , count to do mining rights , resources tax and other expenses have been significantly higher than the current 170,000 yuan to 180,000 yuan per ton, the price of minerals integrated , leading it difficult for the law-abiding business following .

Experts said that the current rampant illegal sales of rare earths , organize special activities are necessary to combat , but in the long term , " warfare " can only be a moment of onset , to eradicate "black rare earth" , to promote the healthy development of rare earth industry must explore the establishment of long-term mechanism to institutionalize the management measures , normalized.

Japanese media: North Korea found that the largest rare earth mine or break China "monopoly"

According to Japanese reports, the British company called SRE Mining Limited announced the reserves of rare earth oxides on North Korea to assess the results . The most striking is that the company claims an estimated 216 million tons of Dingzhou ore containing rare earth oxides, rare earth elements , including light , heavy rare earth elements and rare earth minerals. According to Voice of America radio reports, which will make the world's rare earth oxide reserves increased by about twice as much. USGS recently estimated that global reserves of 110 million tons of rare earth oxides .

Reported that rare earth elements are used from mobile phones to guided missiles and many other cutting-edge technologies. Although extremely rare earth elements are not rare , but Chinese control over 90% of the market share , as in the mining of rare earth , China 's laws and regulations relaxed than in Western countries . China past performance of such a tendency from time to time , namely the use of its near-monopoly of rare earth elements in the political disputes to seek advantage over other countries.

Reported that the outside world has long been known that North Korea has a considerable underground reserves of rare earth and other mineral deposits , it is estimated that the value of SRE Mining Limited reserves is much higher than the previous judgment . Theoretically , this finding may break Chinese control of the rare earth market , because North Korea has to reach China 's rare earth reserves of more than 6 times. In addition, as in developed countries like North Korea without consideration of environmental regulations and labor conditions of exploitation of rare earth elements .

Nevertheless, significant barriers still exist to suppress expectations . The challenge now will be how the mining of rare earth and then shipped to foreign markets in North Korea. In addition to the technical challenges involved are North Korea's political environment so that foreign companies working in the country is extremely difficult to carry out , which limits the ability to exploit its huge mineral wealth in Pyongyang in the past few decades .

Reported that in December last year when the assessment results , SRE Mines Ltd. also revealed that the company has with North Korea trade in natural resources companies formed a joint venture company called Pacific Century Rare Minerals Ltd. , with the rare earth market. This joint venture will be located in the British Virgin Islands , it may be because SRE Mines Ltd. in trying to circumvent sanctions.

Pacific Century, the company has been awarded a 25-year contract to develop Dingzhou rare earth mine . Alleged that the company intends to build a factory on the rare earth deposits . But the report said the North Korean regime has abruptly canceled a long-term contract to foreign companies long history , sometimes just impulsive , but sometimes also because political relations with foreign firms Country Pyongyang appeared changed.
