Rare heavy metal great harm to human body

In this context , the department proposed rare earth content Fuzhou source water monitoring research programs , will introduce the emission spectrum of American mass production , monitoring of drinking water in the rare earth content . Rare earth lanthanum (lán), cerium (shì), praseodymium (pǔ), neodymium (nǚ), promethium (pǒ) and other 10 kinds of elements collectively , while emission spectra mass spectrometer can identify most of these different elemental composition slight difference.

It is reported that many rare and iron ore, uranium associated pollutants , heavy metal poisoning. Rare case of excessive inflow of water , the equivalent of heavy metal pollution of water bodies , human intake , it will affect the nervous system , can cause serious and even kidney failure.

Rare earth is divided into light and heavy rare earth, rare earth south mostly light rare earths. Light rare earth mining basic principle is to use ammonium sulfate soaked soil, the REE ionic displacement to the solution, and then precipitated oxalic acid or ammonium bicarbonate rare earth concentrate .

Small workshops brutal exploitation of rare earth , it is likely to cause pollution. Illegal mining of rare earth who dig the mountain , from the foot of pumping , in the Peak dug pond, open perfusion chemicals soak mined. Perfusion of chemicals directly into the ground , mining and soil contamination of sewage water , land .

Some rare earth potential illegal incorporation of water source protection zones

In addition to the rare earth content in the source water to strengthen monitoring , the province has begun to strengthen some rare earth producing water source protection . Reporters learned that, last September , Dong Tong minqing Sakamoto Sakamoto , Xian Ke Yangshan investigated and dealt with under the illegal mining of rare earth ore events. The provincial government approved the agreement last month to designate Township Minqing three other three towns as centralized drinking water source protection areas, which will contain Dong Tong Sakamoto Sakamoto water source protection zones.

According to reports, after the water source protection areas delineated , the film area will be more stringent environmental requirements , which would be better to curb illegal mining of rare earths impact on downstream drinking water .

Shouning County People's Procuratorate accused , by the end of November 2011 Lunar New Year , the defendant Yemou Zhong , Liu Moumao , Linmou Ming and Lin Moufu , Lin Mouqing ( both handled separately ) and the " Qiu boss" ( specifically unidentified ) six persons jointly , the co-financing 400,000 yuan , in the town of Mei Yeung ShouNingXian Wuqu mountain ridge after undocumented exploitation of rare earth minerals , which Yemou Zhong , Lin Mouqing , " Qiu boss" 15% each , 20%, 50 % of the shares , Liu Moumao , Linmou Ming , Lin Moufu shares were 5% each , divided according to the proportion of shares . As of March 10, 2012 , six people through the sale of finished rare earth ore illegal profit 110,000 yuan , of which Ye Mouzhong share 16,500 yuan , Liu Moumao , Lin Mouming each share 5,000 yuan. Identified by the Fujian Provincial Department of the minerals to weathering crust ion adsorption type rare earth mine , because undocumented exploitation of rare earth mineral resource damage resulting value of 89,300 yuan . Public prosecutor that the three defendant's conduct has violated Penal Code section 343 first paragraph , the first paragraph of Article 25 provides that illegal mining should be held criminally responsible .

Praseodymium neodymium rare-earth prices steady vulnerable No large fluctuations

Details: Category: Rare Earth News; Published on Wednesday, 09 October 2013 15:14; Written by HJF; Hits: 1770

Today's increasingly rare earth market vendors offer price or stable or slightly adjusted , traders have some inquiries and purchase , the current rare earth market as a whole remained stable.

Praseodymium neodymium market today Ganzhou region with a ticket vendor praseodymium neodymium offer 440,000 yuan / ton, slightly lower than before the holiday a little five thousand dollars / ton. There are local traders reflect lower market some sources. And it means that other suppliers with a ticket price of neodymium praseodymium 45.5-46 yuan / ton or so , the market price did not change significantly . Praseodymium neodymium oxide market , the industry reflects the current market price at 34.5-35 yuan / ton before the holiday less.

Dysprosium products market , current prices remain weak steady, thinly traded . Dysprosium oxide with ticket prices remained at 200 yuan / ton, dysprosium iron with ticket prices at 205 yuan / ton or so, with the final prices were unchanged in September .

Neodymium oxide market today , some traders deliberately shill , offer to 360,000 yuan / ton , reflection, although the market is not good, but not cheap shipping , other suppliers reflects neodymium oxide with ticket prices remained at 34 -35 yuan / ton.

Europium oxide market, there are a small number of inquiries, the market traders reflect europium oxide spot with a ticket price of 480,490 yuan / ton, compared with before the price almost no major changes , businesses offer a smooth firm.

Waste magnetic electric car market today, there are still many recyclers do not offer a slightly lower offer 1-2 yuan / kg or maintain previous levels , currently Linyi region recyclers reflect temporary stay on the sidelines of the market , prices temporarily make adjustments , electric car brushless motor scrap 81-82 yuan / month, short of 94 yuan / kg, long 104 yuan / kg.
