Japan developed from a scrap of high purity rare earth extraction technology

Tsutomu Yamaguchi, Japan Iwate University professor functionality JX Nippon Mining and Metals Corporation jointly developed the stone from scrap cars and home appliances magnet high efficiency recovery of rare earth metals technology. The waste was added boron magnet, is heated to 1200 degrees Celsius, the heating of raw material is acidified boron, a mixture of neodymium and dysprosium, iron, and carbon, nickel alloy blocks, etc., and then extracted with hydrochloric acid, such as neodymium, at a temperature of 400 ~ drying temperature of 500 degrees for 1 hour. According to the experiment, the recovered rare earth metal up to 99.5% purity.

Previously, researchers have been hand-stripped abandoned nickel, crushed after adding hydrochloric acid solution to recycle rare earth metals. However, due to hand and an acid reaction, recovery time takes a full day. The new technologies do not peel off due to nickel can be recovered with a half-time completion, and recovery costs.

Professor Yamaguchi current problem is how to remove harmful substances when recovered, once the issue is resolved that the technology will soon be able to get practical.

Permanent domestic rare earth market recovery helped July rebound

Rare earth prices since 2011 has been a sharp correction, there had been two domestic sizable rebound rate were about 30%, the time span of about two months.

In late June onwards, some rare varieties prices rebound. As downstream demand increases to get the support of an institution may be expected in July will continue to rally.

In late June of this year so far, on behalf of heavy rare earth metal dysprosium, SMM offer 2500-2700 yuan / kg, an increase of 18%, light rare earth oxide, praseodymium representatives, SMM offer 38-39 yuan / ton, an increase of 12%. However, the domestic downstream despite a slight recovery, but demand is still sluggish.

According to the survey, the current downstream enterprises operating rate compared with the second half of 2012, mostly restored to the level of 7 percent, mainly because of cars, air conditioners and electronics permanent markets more stable overall demand in coming months. But even so, it's still difficult to support long rare earth prices rally.

In addition, the domestic inter-provincial corporate reluctant to sell to combat illegal mining is certainly very good for price, but China is still the biggest problem facing the rare earth industry consolidation in the industry.

WTO action against China rare earth is still in progress, the Chinese side to get the low probability of success. This will force China to further accelerate the integration of rare earth concentration of production capacity, thereby forming a price protection mechanism, and only that, the future is more rare earth prices rebounded solidly secure.

July 5, 2013 is still strong market demand for rare earths

Core Tip: rare return to the mainstream market quotations, Eu Tb Dy offer somewhat lower, the market turnover is still flourishing. , A slight increase in the price of neodymium oxide, praseodymium, neodymium, praseodymium metal prices remained level the day before yesterday. Praseodymium neodymium oxide supplier indicates the current spot is not, do not choose cheap shipping.

It is understood that a metal factory in Ganzhou area reflects a slight increase in the price of neodymium oxide, praseodymium, neodymium, praseodymium metal prices remained level the day before yesterday. Praseodymium neodymium oxide supplier indicates the current spot is not, do not choose cheap shipping, the current mainstream market with fares at 28-28.5 yuan / ton or so, with no votes in the 24-25 yuan / ton. Praseodymium neodymium metal mainstream market prices remained stable, with fares at 360,000 yuan / ton. There Ganzhou Insiders said late price declines likely.

The market price of dysprosium oxide slight pullback, the market traded price return, according to insiders now reflect dysprosium oxide with votes already have 1.4 million yuan / ton traded, while other market participants reflects the mainstream market price of 150 yuan / ton. Today dysprosium iron straps fares remained at 155-160 yuan / ton price, no significant change.

This week lanthanum, cerium market, metal lanthanum, cerium metal hovering low price, lanthanum oxide, cerium remained stable, quoted in the mainstream 2.8, 2.9 yuan / ton or so. Lanthanum cerium downstream demand is still weak, the market is less purchasing behavior.

Before Eu terbium oxide suppliers offer unrealistically high, but the market is not hot deal, due to lack of demand strong support, most vendors the price correction, the current mainstream market prices come down significantly. According to Ganzhou region reflects traders intent to purchase on the market now mainstream fare in europium oxide with 360-380 yuan / ton, terbium oxide gap between market price, a price in the 290-320 yuan / ton or so.

Magnetic scrap market, overall prices showed a rising trend this week, inquiries have increased. Today, there is no obvious change in the market price of the mainstream, small retail is still in the hands of large volume, the larger the amount of more stock traders. Waste Electrical and recently traded slightly active, because copper prices compared with the previous price before still no advantage, market prices did not recover a substantial adjustment, Linyi and Zhejiang region today brushless recovery price 74-75.5 yuan / month, brush 115-125 yuan / month.

Guangxi will strengthen the protection and development of rare earth

Guangxi Zhuang Autonomous Region Vice Chairman Lin Nian Xiu recently given instructions to Land and Resources Department of Guangxi and Guangxi to Guangxi CAST experts in the field of rare earth rare earth protection and development deepen research, to make specific comments. From far has proven ore reserves of rare earth look, Guangxi, the country ranked fourth rare earth reserves, including reserves of rare earth ion-adsorption type ranked first. For the development of rare earth industry in Guangxi exist poaching selling stolen, waste of resources, environmental pollution and other issues, relevant experts and technology workers to the government submitted a "stop wasting behavior of rare earth resources and pollute the environment, the proposal to build a beautiful Guangxi" I hope to further regulate rare earth mining order to speed up transformation and upgrading of the rare earth industry, strengthen the innovation capacity-building and comprehensive management of environmental pollution.
