RE market trends remain stable this week , traders generally reflect weak downstream demand , turnover deserted. Currently the price of some products at a low position, but also affected the demand , there is a large price changes difficult aspects , some suppliers eager to slightly reduce the price of shipping to ship , but there are people in the industry even if the price reflects the turnover situation is not satisfactory.

This week dysprosium oxide market prices basically stable , some traders continue to consider price cuts will lose , unwilling to continue shipping prices , quotes always at 180 yuan / ton, steady dysprosium iron market prices , according to Ganzhou supplier feedback now with no votes Price 153-155 million and also manufacturers offer slightly higher at 1.58 million yuan / ton. Terbium oxide prices slightly lower this week , a small Inquirer small orders , supplier quotes slightly by 100 yuan / kg , the price of europium oxide is also flat or slightly down , as light turnover .

Praseodymium , neodymium market , manufacturers and traders from the quotation , this week basically no price adjustment , Ganzhou and Shanghai area suppliers offer basic at 40-40.5 million / ton, shipping situation is not good . Praseodymium neodymium oxide market , vendors shipped actively traded flat or slightly lower prices and last week's 2-5 thousand dollars.

Lanthanum, cerium class , according to the current factory in Baotou and Ganzhou feedback lanthanum oxide , cerium oxide prices basically unchanged. Ganzhou by local businesses offer , 3N lanthanum oxide are still 23,000 yuan / ton , 3N cerium oxide in the 22,500 yuan / ton, Baotou both manufacturers said the price is still about 26,000 yuan / ton.

This week the price of neodymium oxide is difficult to adhere to as well , the current price is slightly down compared with last week -1 5,000 yuan / ton , the business outlook is still considered likely to continue to decline. Erbium oxide market price is relatively stable, there are downstream manufacturers that may be difficult for the purposes of purchasing and storage , the market is not worried about sourcing suppliers offer relatively stable at 35-36 yuan / ton.

December 7 , Zhejiang sixth academic report analyzing test was held in Hangzhou. The meeting by the Zhejiang large scientific instruments and analytical writing shared management office hosted Testing Association , Zhejiang Province , attracting industry experts , efficient, and many famous enterprises on behalf of more than 600 active participants , to discuss environmental monitoring , food safety, health and quarantine application and development of instruments and other fields . During the meeting, Sun Chaoyang from the Institute of Geology and Mineral Resources of Zhejiang Province as a " test method REE carbonate rocks " reports.

We know that the determination of rare earth elements for geological age, explain the causes of the demo minerals , diagenesis and mineralization of geochemical conditions , material sources , magma evolution provide useful information. As a geochemical study of rocks and minerals , " showing Chen agent" is widely used in the field of modern geological science , and REE and trace elements can help restore a variety of original rock characteristics determine the tectonic setting of its formation.

Spectrophotometry is commonly used test methods of rare earth elements , rare earth elements are widely used in various types of analysis and testing samples . With the continuous improvement of synthesis technology , many new chromogenic reagent REE be applied , although the sensitivity and selectivity spectrophotometry has been greatly improved , the stability has also been enhanced , but still can not meet the requirements of the detection limit difficult to achieve measured REE component . Although genetic spectrophotometric simultaneous realization of multi-component determination of rare earth , but to chemometrics , operate more complicated, in practical applications easily restricted. The biggest drawback XRF determination of rare earth elements is less than the detection limit , it is difficult to test geological samples used in the analysis of trace rare earth.

Inductively coupled plasma atomic emission spectrometry (ICP-AES) has the advantage of a wide range of linear and multi-element determination , has become an important means of analysis of rare earth elements , but the direct determination of analytical sensitivity can not meet the requirements , then , there is more severe matrix effects , spectral interferences and other issues. Therefore, these methods have lost their superiority , unable to meet the current Analysis of Rare Earth testing requirements.

Finally Sun Chaoyang come Summary: Inductively Coupled Plasma Mass Spectrometry (ICP-MS) with high sensitivity , low detection limit , can be directly measured REE carbonate rocks . For some carbonate rocks, using hydrochloric acid, nitric acid, hydrofluoric acid, lactic acid, sulfuric acid decomposition easily lead portion of the heavy rare earth analysis of low sodium oxide should be melted decomposition. Since no suitable means of chemical separation of europium barium content will bring high sample error Jiaotong University , the exact exchange resin separation should be determined by barium or measured using high-resolution ICP-MS .

Advantages for the protection and rational utilization of resources , the " rare earth kingdom ," said the main origin of the world's rare earth ions in Ganzhou , Jiangxi introduction of such notice , sought by a number of measures to promote tungsten and orderly development of rare earth resources , sustainable use .

The State Council issued the " Opinions on Promoting the sustainable and healthy development of rare earth industry ," noted that the top three companies southern ionic rare earth industry concentration to 80 %, but since most of the rare earth resources in the hands of local governments and enterprises , at present, Southern ionic rare earth industry consolidation is still the main driving force is actually the local government .

In the new introduction of Ganzhou , " issued in 2011 on the city's tungsten , rare earth ore mined total control indicators notice " that the county district to strictly implement the tungsten ore, total rare earth mine control targets. Nanjing County continues discontinued, Gan County , Xinfeng principle discontinued - by the end of 2011 counties halted .

Meanwhile, the total amount required to strengthen urban counties control indicators of the implementation of the mining law enforcement .

In fact , a few months ago Ganzhou city's rare earth industry in depth unprecedented " revolution" , many mines have been shut down for rectification. The industry believes that the move will intensify in the second half of Ganzhou Rare Earth Resources tight supply situation to some extent .

Six ministries rectify rare earth production

Our great country is rare , reserves and production are among the first in the world .

Since last year, prices of many rare earth products rose yuan per ton day rate "rocket " up . According to data platform commodities business community on September 2 released data show that from the beginning to the end of August , some rare earth products rose more than 700 percent .

This year on July 25 , the Ministry and other six ministries jointly issued a notice , for no instruction production, ultra- command production , backward technology and not by environmental verification of rare earth mining enterprises , the requirements shall be discontinued, rectification, otherwise it will severely punish even hanging ( Note ) off the relevant license .

Most of Ganzhou Rare Earth Mining Discontinued

Ganzhou because they have more than 30% of the country 's heavy rare earth reserves , known as "rare earth kingdom ."

Local Ganzhou Rare Earth Resources , unified management by the Ganzhou Rare Earth Mining Company . The relevant responsible person said Ganzhou Mining will strictly implement the relevant notification , involving rare earth mine to suspend production areas . Ganzhou middle of a separation plant sources, Ganzhou mining has stopped for each mineral separation plant , only big business for individual mines .

Another private Ganzhou separation plant official told reporters , in fact, before the State Council issued the "Opinions" , Ganzhou Rare Earth Mining District, most has been discontinued, because production targets exhausted and environmental verification.
