Uses of Rare Earth Elements

Details: Category: Rare Earth News; Published on Thursday, 04 September 2014 15:54; Written by jwy; Hits: 2251

Rare earth metals and alloys that contain them are used in many devices that people use every day such as computer memory, DVDs, rechargeable batteries, cell phones, catalytic converters, magnets, fluorescent lighting and much more.

During the past twenty years, there has been an explosion in demand for many items that require rare earth metals. Twenty years ago there were very few cell phones in use, but the number has risen to over 7 billion in use today. The use of rare earth elements in computers has grown almost as fast as cell phones.

Many rechargeable batteries are made with rare earth compounds. Demand for the batteries is being driven by demand for portable electronic devices such as cell phones, readers, portable computers, and cameras.

Several pounds of rare earth compounds are in batteries that power every electric vehicle and hybrid-electric vehicle. As concerns for energy independence, climate change and other issues drive the sale of electric and hybrid vehicles, the demand for batteries made with rare earth compounds will climb even faster.

Rare earths are used as catalysts, phosphors, and polishing compounds. These are used for air pollution control, illuminated screens on electronic devices, and the polishing of optical-quality glass. All of these products are expected to experience rising demand.

Other substances can be substituted for rare earth elements in their most important uses; however, these substitutes are usually less effective and costly.

From the 1950s until the early 2000s, cerium oxide was a very popular lapidary polish. It was inexpensive and very effective. The recent price increases have almost eliminated the use of cerium oxide in rock tumbling and the lapidary arts. Other types of polish, such as aluminum and titanium oxide, are now used in its place.

What Are Rare Earth Elements (REEs)?

Details: Category: Rare Earth News; Published on Thursday, 04 September 2014 15:50; Written by jwy; Hits: 2081

Rare earth elements are a group of seventeen chemical elements that occur together in the periodic table (see image at right). The group consists of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium). Scandium is found in most rare earth element deposits and is sometimes classified as a rare earth element. The International Union of Pure and Applied Chemistry includes scandium in their rare earth element definition.

The rare earth elements are all metals, and the group is often referred to as the "rare earth metals." These metals have many similar properties and that often causes them to be found together in geologic deposits. They are also referred to as "rare earth oxides" because many of them are typically sold as oxide compounds.

India Inches into the Rare Earth Market

Details: Category: Rare Earth News; Published on Wednesday, 03 September 2014 14:20; Written by jwy; Hits: 1140

To say China is the main player in the rare earth element (REE) space is, of course, an understatement. The country lost an appeal regarding a World Trade Organization (WTO) ruling on its REE export restrictions last month, but it still controls the lion’s share of the market; that means any indication that another entity might take a share of the market, however small, is definitely worth some attention.

According to Reuters, India is commissioning a plant that will produce as much as 5,000 tonnes of REEs annually. S. Surya Kumar, head of state-owned Indian Rare Earths’ Rare Earths Division, has not given a timeline for the plant’s development, but did say that it will be located in Odisha and will produce rare earth oxides by processing monazite from beach sand.

Once the plant is up and running, India could stand to contribute approximately 5 percent of global supply.

Japan, like the rest of the world, relies heavily on China for REEs. However, the resource is even more important for the island nation as REEs are necessary for the production of the electronics and computerized systems that make up a substantial portion of Japan’s exports.

It isn’t surprising then, that a subsidiary of Japan’s Toyota Tsusho (TSE:8015) has a hand in the newly commissioned Indian plant. Indeed, it’s already entered an agreement for half of its anticipated production. The partnership between the two looks to be going well so far, as International Business Times reported that Indian Prime Minister Narendra Modi met with Japan’s Shinzo Abe this week to discuss the contract further. Japan has also committed to doubling its overall direct investment in India over the next five years.

Japan intends to co-production with India in the field of electric vehicles for rare earths

Details: Category: Rare Earth News; Published on Wednesday, 03 September 2014 16:04; Written by HJF; Hits: 2078

It is reported that Japan will sign an agreement with India, scheduled for 2015 co-production of rare earths in India, in order to reduce dependence on China in this regard.

According to Nikkei Shimbun reported that Indian Rare Earth (Indian Rare Earths) as early as September signed an agreement with Japan's Toyota Tsusho to conduct a joint production of rare earths.

Indian RE company will produce uranium, thorium and other mixed rare earth materials, and supplies to Toyota Tsusho, which will use these materials for electric vehicles and hybrid vehicles, and other fields.

Supply will begin early next year in February, the annual production of rare earth about 2,000 to 2,300 tons, the equivalent of Japan's overall demand for rare earths by 15%.

China's rare earth production accounts for over ninety percent of global output, the past few years, the Chinese government gradually restrict the export of rare earths, Japan has been trying to reduce its reliance on China in this regard.

India is expected to account for 5% of rare earth supply worldwide

Details: Category: Rare Earth News; Published on Tuesday, 02 September 2014 16:09; Written by HJF; Hits: 2174

According to reports, India's state-owned enterprise executives recently said that the Indian government is entrusted to a factory of 5,000 tonnes per year of rare earth production tasks. Thus, India is expected to achieve total global rare earth production accounts for 5% of the share. Despite India's production is not high, but for Japan and other countries, but it is good news.

India's Department of Atomic Energy is part of state-owned enterprises & mdash; & mdash;?? Indian Rare Earth RE department head S Zulia Kumar (S.SuryaKumar), said the plant will be located in India Bangaoli Sabangfrom beach sand through processing monazite soil to produce rare earth oxides. Production of rare earth in about half will be used for processing into lanthanum and cerium. These two elements are mainly used in the manufacture camera lens and glass polishing agent.

Kumar also said that Indian Rare Earth Company and Toyota Tsusho Corporation's Indian subsidiary abundance of rare earths have agreed to pass the two sides will work together to share the production of 5,000 tons of rare earth.

Japanese Economic News recently reported that Indian Prime Minister Modi (NarendraModi) will soon visit Japan, India is expected rare earth companies will be jointly produced with Toyota Tsusho on the issue of mixed rare earth sign a further agreement.

RE known as & ldquo; industrial vitamins & rdquo; reputation, has become an extremely important strategic resource, which in the field of petroleum, chemical, metallurgy, textiles, ceramics, glass, permanent magnet materials play an important role. REE oxides refers to the periodic table with atomic numbers 15 kinds of lanthanide oxide 57-71, and lanthanide oxides with similar chemical properties of scandium and yttrium total of 17 kinds of elements. With the continuous advancement of technology and breakthroughs in the application of technology, the value of rare earth oxides will be increasing.

According to RE ownership (including ore and semi-processed products), China, Russia, the United States, Australia is the world's rare earth has four major countries, China ranked first, accounted for 90 percent of the global total.
