LED phosphor rare earth prices dropped by 52% -83%

U.S., EU and Japan in 2012 to the World Trade Organization (WTO) complaint , which means that the continent restrict exports of rare earths is a violation of WTO rules in practice . WTO has made a ruling on March 26, 2014 , ruling on the complaint of state benefits .

Although the United States , the EU and Japan in the WTO to win the round , but in fact the same time early in their appeal , have already begun trying to reduce dependence on the mainland rare , once rare because the continent as a military and diplomatic negotiations outside chips. Up to rare earth imports from mainland Japan, for example , has sought to diversify alternatives , such as rare earth ore imported from Australia, India, investment in the production of rare earth, even to replace other materials such as rare earth , therefore , in the world's rare earth monopoly position in the continent decreasing , also led to rare earth prices fall.

From 2014 rare earth export quota for mainland point of view , representing a decrease of approximately 30% in 2013 , mainly due to exports of rare earths in 2013 is lower than the actual amount of that year 's quota , the 2014 quotas are adjusted accordingly . Also, according to industry research of rare earth observation monthly price changes associated with the LED cerium rare earth metals, metal yttrium , terbium oxide , in March 2014 the price was reduced rates were 38.1% , 0%, 41.3% , if the 2012 compared highs , down as much as 52 to 83 percent , this display with LED phosphors past tense situations expensive now appear soothing .

The new exam promotion of new energy vehicles: Rare pollution

New energy vehicles , especially pure electric vehicles because they do not fuel , less emissions , become synonymous with environmentally friendly fashion . However, the upstream and downstream industry chain will bring pollution may surprise people . For the pollution generated by new energy vehicles , most people understand the current generation of pollution is : that although the process of using electric cars to achieve a zero- emissions, power generation plants has caused severe dust pollution . Especially in China , more than 75% of its electricity from coal power generation, no less than the dangers of pollution gasoline combustion .

In fact , the new energy vehicle industry chain downstream pollution caused by much more than that . For example , the use of new energy vehicle batteries , in the production process will produce pollution. Graphite is the constituent elements of the electric car lithium batteries , there are foreign media said , per pure electric car contains about 50 kg of graphite , containing about 10 kg of hybrid , electric bicycles containing about 1 kg , notebooks containing about 100 grams , the phone contains about 15 grams. Graphite manufacturing process will contain large amounts of heavy metals discharged highly acidic wastewater , contaminated farmland and drinking water, graphite dust floating into the air will cause "Black Rain " and the haze phenomenon .

Currently , lithium batteries have become the mainstream choice of new energy vehicles , but still the majority of low-speed electric vehicles in the use of lead-acid batteries, lead-acid battery production process will generate a lot of lead dust , lead acid mist , waste water, waste gas . Lead is a toxic heavy metal that can enter the body through the respiratory and digestive systems , can also lead to babies through breast milk embryos and poisoning . Lead enters the human body , can diffuse from the blood into the soft tissues and organs of the body , and ultimately into the bones and teeth , resulting in major diseases .

Improper recycling of used batteries will produce more pollution. Used batteries contain cadmium , lead, mercury , nickel, zinc , manganese, etc. , will affect seed germination and growth , resulting in pollution of rivers, lakes, sea and other water bodies , where the cadmium, lead , mercury would be more interested in bring great harm to the human body . Data show that a small lithium coin can contaminate 600,000 liters of water. Similarly, the lead-acid battery if mishandled , the greater harm.

Rare chronic pollution is another new energy vehicles can not be avoided . Rare is called " industrial vitamins ' extensive use in military, electronics and other industries , is an important strategic mineral resources. Batteries and new energy rare earth permanent magnet motor cars also use rare earth materials . For example, some high-performance electric vehicle equipped with synchronous motor on the use of rare earth materials .

However, the rare earth ore open pit mining process will produce radioactive pollution , heavy metals, fluoride , ammonia and sulfate pollution, recycling of resources , the surrounding atmosphere , plants, aquatic ecosystems , soil environment has potential hazards. Some areas also because overexploitation of rare earth , causing landslides , river blockage, sudden environmental pollution and other events. After the rare earth mining , mine environment restoration and management is also a heavy burden.

Rare minerals Chaoshan region is very rich. 2013 , due to a lawless region of Guangdong Lufeng illegal mining of rare earth , resulting in a number of villages around the water undrinkable . 2011 , also because of a rare earth mining Chaoshan area of environmental pollution , caused by local villagers and fight illegal mining . Local villagers told reporters that because of pollution caused by illegal mining of rare earth , they did not dare to drink water Curry , near the Castle became the Loess Plateau . Kids go swimming in the river bathing has become memories.

Another concern is that China 's rare earth resources face depletion problem. State Council Information Office published in 2012 , " China 's rare earth conditions and policies ," the white paper said China's rare earth reserves account for 23 percent of global reserves, has supplied 90% of global demand . After half a century of mining super strength , China's reserves of rare earth resources and the protection of life continue to decline, decay accelerating major mining resources , most of the existing mining resources depletion .

White Paper For example, Baotou rare earth ore mining resources remaining major 1/ 3 , Southern ionic rare earth ore reserve-production ratio has been 20 years ago to the current 50 15 . In view of this , if a large -scale promotion of new energy vehicles , it is not only rare earth mining will become a stumbling block pollution caused by rare earth is a strategic non-renewable resources , depletion of rare earth will also affect the production of new energy vehicles , as oil depletion will draw fuel vehicles on the same period .

Face generation of pollution , the industry 's response is that the new energy vehicles during the day and electricity at night to charge , you can reserve the power grid can not fully use , reduce energy consumption, while , to promote wind power and hydroelectric power and other green energy . The face of pollution and recycling pollution caused by battery production , the country has developed a unified approach to battery recycling management , and greatly enhance battery production and recycling technology. For the rare earth mineral depletion of the country 's current practice is strictly managed rare earth mining , improve the comprehensive utilization , regulate the export price.

Anyway , enough battery energy density , inadequate facilities , state subsidies and other factors are not in place just dominant disorder promotion of new energy vehicles , battery pollution , the pollution caused by the mining of raw materials and resource depletion, may be hidden behind the scenes bigger stumbling block . How these hurdle crossed , will test the wisdom and courage to promote new energy vehicles persons .

Increase the number of rare earth mining enterprises listing price, waiting for the ground state purchasing and storage rumors

Chinese exports of rare earths in the preliminary WTO Dispute occasion lost since April 2 , Minmetals Rare , Rising colored aluminum and rare earths in (Jiangsu ) companies have been way higher than the market average listing price of rare earth products , directly contributing to the some rare earth prices, two rare earth stock market-related collective "rosy ."

Insiders believe that behind this rumor closely with the national purchasing and storage of rare earth , some businesses have begun to stockpile the sidelines , waiting for the rare earth prices move up , however , under the demand is low, rare earth prices will eventually fall.

Shouchu renewed rumors

No listing for several months of rare earth enterprises , announced a new one rare earth oxide listing price . April 2 , Minmetals Rare Earth Research Institute Ltd. pioneered listed price of rare earth oxides , April 3 and April 4 , Rising ferrous and aluminum in rare earth ( Jiangsu ) Co., Ltd. have also announced the listing price of rare earth oxides .

Public information, April 2 Minmetals Rare Earth hanging ticket price : praseodymium , neodymium 360,000 yuan / ton, praseodymium oxide 600,000 yuan / ton, neodymium oxide 360,000 yuan / ton.

After a continuous increase on April 3 and 4 days , neodymium oxide, praseodymium Minmetals Rare Earth directly from 360,000 yuan / ton up to 385,000 yuan / ton , praseodymium oxide from 60 yuan / ton up to 640,000 yuan / ton, neodymium oxide from 36 yuan / ton up to 385,000 yuan / ton.

Disclosure of China Rare Earth Industry Association website price displayed , April 3 , praseodymium , neodymium price of 32 yuan to 334,000 yuan / ton , which means Minmetals Rare Earth Rising colored and about 15 % of the market price listed above .

" Now the market rumors of rare earth Shouchu lot , sources said on the 10th or the 11th state will be purchasing and storage , but a few days ago did not exactly news. "rare earth industry analyst Du Shuai soldiers on the" Daily Economic News " reporter said .

"A lot of businesses are in a wait state stockpile , hope after purchasing and storage price has pulled up the difference by making a profit . "Du Shuai Bing said .

Du Shuai soldiers analysts said the overall light downstream demand , the downstream demand of rare earth magnetic material is the greatest , and no great demand pulled , was the result of some rare earth prices rebounded to varying degrees , may be associated with purchasing and storage of rare earth market expectations related.

The rare earth industry analyst许海滨also said that "national purchasing and storage of rare earths can be determined basically the message , but the number and timing of specific species are yet to be finalized . "

" Listed companies here have not yet received the relevant notification , the listing price higher than the market price of around 10 %, with some rare Shouchu expected , if the State Reserve Shouchu will receive timely disclosure . " Minmetals Rare securities department official told reporters . Baotou Steel Rare Earth securities who have similar expressions .


Boost prices
World Trade Organization (WTO) panel report released recently rare cases , finds China 's rare earth export taxes and other related products and export quota management measures violations, for many years, rare earth export quotas will face cancellation .

In the downstream demand is low and Chinese exports of rare earths dispute case against the preliminary ruling under on the market to boost the state purchasing and storage of rare earth rare earth prices is also expected to gradually stronger.

In accordance with past practice, when the country usually commissioned at the end of large-scale enterprises purchasing and storage of rare earth , rare earth prices in the last half year the average price of purchasing and storage price . The rare earth rare earth companies to raise prices and consistent approach to its favorable results . But at the end of last year , the market expects the national RE Shouchu did not occur.

" Under the WTO case against the preliminary ruling , the state purchasing and storage of rare intensity may be larger, the rare earth prices pulled up, " Du handsome soldier , told reporters that " Thus, in the case of export quotas , prices can be higher . "

Meanwhile, Du Shuai soldiers think that the market is expected to drag on purchasing and storage of rare earth a long time , the market is more sluggish mentality parties , countries may wish to boost market confidence.
