New Wire Shape Eliminates Rare-Earth Magnets

Some of the world’s most powerful magnets, not including electromagnets, are made from the rare-earth metals neodymium, samarium, or yttrium. As a result, Italian and Indian Research – Cheap and Safe Hydrogen Production are expensive, while magnets made of iron, ferrite magnets, are cheaper, but not nearly as strong.

Electric motors only function because of magnetism, and can be made up of arrangements of electromagnets and permanent magnets. By replacing ferrite magnets with neodymium magnets, an electric motor bound for an electric vehicle [EV] can be made smaller and lighter, weight being an important consideration in such an application.

In order to reduce dependency on rare-earth magnets, and therefore costs, Yaskawa Electric set out to produce an EV motor with a ferrite magnet core. The problem with the ferrite magnet, though, was strength, so Yaskawa had some work ahead of it to maximize the power output of the weaker core. First, the shape of the magnet had to be optimized to improve torque output.

Then, Yawaska made a change to the coil wiring itself. Instead of using the standard round-cross-section wiring, Yawaska switched to a rectangular-cross-sectioned wire, which stacks better on the rotor and stator. This resulted in a 30% increase in the number of windings they could put in the same space, increasing the power output over the standard round wire motor.

The resulting EV motor, about the same size as currently found in EVs and hybrids, weighs about 132 pounds and maxes out at 12,000 RPM. With a maximum power output of 80kW and 147 hp at zero rpm, the new motor fits in the range of what’s required for a small EV or hybrid vehicle.

By eliminating rare-earth magnets and combining new processing and optimization, the result is a cheaper motor, which would help to reduce costs of EVs and hybrids alike. Reducing costs would certainly help marketing these high-technology vehicles and help them gain acceptance in such a difficult market.

Rare Earth Elements Could be the Source of Clean Energy

Although they might have archaic-sounding names to the public, dysprosium, terbium, europium, neodymium and yttrium because of their rarity hold the secret to future technology as well as the success of clean energy and they are preoccupying the most powerful nations of the world.

Gaining access to these elements is a priority for U.S. energy strategy, which sees that China controls 95 percent of the production of the so-called rare earths, which are used in wind turbines, solar panels and the batteries of electric and hybrid vehicles.

With that situation in mind, the U.S. Energy Department mobilized scientists and experts from business and academia to seek solutions, a team that will be part of the new Critical Materials Institute.

Iowa-based Ames Laboratory and its director, Alex King, are heading up the project, which will receive $120 million in financing over the next five years.

The main aim of the CMI in the short term will be to detect possible deposits of these metals in the United States, as well as to work with existing operations to ensure that they are viable.

King gave the example of the Mountain Pass mine in California, which for decades was the biggest supplier in the world for rare metals but had to close in 2002 due to environmental problems.

The mine reopened in 2010, although it is facing a difficult market situation given China’s exercise of price controls by restricting rare earth exports.

That practice has been denounced by the European Union, the United States and Japan, while China insists that its intention is to put the brakes on excessive production to lessen environmental damage.

TUC Resources Soars on Heavy Rare Earths Find at Stromberg

TUC Resources shares soar following intersections of very high grades of over 90% heavy rare earth at its Stromberg Heavy Rare Earth prospect in the Northern Territory. Shares were up $0.141 a share, up over 113% before trending down to 96.72% at $0.12 a share.

Diamond drilling at the prospect returned 4.2 metres at 0.93% total rare earth oxide with 92% heavy rare earth oxide and included 3 metres at 1.19% TREO.Other intersections included 3 metres at 0.59% TREO including 1 metre at 1.10% TREO with 94% heavy rare earth oxide.

The clay host rock allows the conclusion that the geological processes that have formed at the Stromberg Prospect are similar to those that produced the renowned Southern China Clay rare earth deposits.

The Chinese rare earth deposits are at the forefront of rare earth production because the majority have very low production costs.

TUC hopes to find mineralisation with similar mineral processing characteristics to these Southern China Clay deposits and theorises its chances of doing so are increased due to the large number of prospects on its ground. It recently made breakthroughs in land access that allows it to target nearby Skyfall and Largo prospects.

TUC intends to focus 2013 exploration efforts on this large district potential with work planned to commence next month. Separately, it has entered into a memorandum of understanding with China's Shandong Provincial Bureau of Geology and Mineral Resources to form an alliance for the exploration of eight heavy rare earth tenements in the Stromberg region.

As part of the MoU, TUC will place 22.5 million shares to Shandong at an issue price of $0.10 a share together with 9 million free attaching options to raise a total of $A2.25 million. The options can be exercised at $0.20 a share before 14 August, 2014.

This new partner would fully fund the feasibility , design and importantly construction in return for a 50% share of that project and certain off-take rights.

Stromberg REE tenements

TUC Resources Ltd holds approximately 15,000 square kilometres of prospective land package across 47 (28 under application) tenements making it one of the biggest ground holders in the Northern Territory of Australia.

Last year, TUC focused on developing its Stromberg heavy rare earth elements project towards resource status with additional metallurgical testing. It also undertook geochemical sampling on the nearby Scaramanga and Knightfall prospects.

The Scaramanga prospect was drilled and yielded promising results with first pass drilling  delineating more near surface mineralisation with a high HREE distribution. Dysprosium, Yttrium and Erbium at a high of 7.5%, 64% and 5% of TREO distribution respectively were found.

Foreign Suitors Including China Eye U.S. Rare Earth Operator

Colorado-based Molycorp Inc. has had nothing but trouble since it reopened the only U.S. rare earth mine a year ago.

Sinking prices have shafted its market value, its CEO Mark Smith departed last month, it’s the subject of an investigation by the U.S. Securities and Exchange Commission, and it faces a lawsuit alleging citing engineering deficiencies at its Mountain Pass, Calif. mine, which Molycorp opened, after years of dormancy, to patriotic cheers last February.

With the plunge in its stock, various industrial companies may now be trying to acquire it at a bargain price to assure themselves a source of the vital metals currently controlled by China, which has a grip on 95 percent of the world’s supply. Manufacturers build rare earths into smartphones, computers, cars, hybrid and electric vehicles, wind turbines, missiles, light bulbs and many other products.

Suitors include German industrial giant Siemens as well as Japanese and South Korean car makers Nissan and Hyundai, according to a Bloomberg story early this month that cited several industry analysts.

“At this point, Molycorp is definitely in play,” Toronto-based Luisa Moreno of Euro Pacific Capital Inc. told Bloomberg. “It would be a very good target for companies that are interested in being in this space if they recognize the rare earth space is important and they have the cash to take Molycorp and make it a real producing company.”

GOIN’ DOWN DOWN DOWN
Molycorp’s difficulties socked investors with a 61 percent loss in 2012, Bloomberg noted. A stock that had traded as high as $77.54 in May 2011 had tanked to $9.44 on Dec. 31, 2012. Shares have been rising recently on takeover rumors.

One rare earth expert doesn’t believe that Siemens, Nissan and Hyundai stand a chance. Rather, China would be the most likely acquirer, further cementing its hold on the market.

“Molycorp has no value outside of Chinese control,” says Jim Kennedy, president of St. Louis-based rare earth and thorium consulting firm ThREEM3, which also owns right to rare-earth byproducts from Missouri’s Pea Ridge iron ore mine. China’s ability to influence supply and prices means that any other acquirer would struggle to survive, he said. “Why would any corporation buy Molycorp when 83 percent of its production will sell at a loss?” Kennedy wondered in an email exchange with me.

MEET ME IN THE MOJAVE

Adding legs to his assertion: According to one source, Chinese government officials recently toured Molycorp’s Mountain Pass facilities in Mojave Desert, near Nevada. They are not interested in the deposit so much as the company’s refining techniques, the source said.

The Chinese government owns many rare earth companies including giant Baotou Steel Rare-Earth. China has recently imposed production and export cuts in an effort to drive up the price of rare earths. It has also undertaken a massive industry consolidation.

One reason that rare earth prices - and thus Molycorp’s share value - tumbled is that manufacturers have been finding ways around their reliance on rare earths.

They have also been scrambling to circumvent China’s control. (Molycorp faced heavy domestic criticism earlier this year when it became obvious that it was selling much of its U.S.-mined rare earths to China.)

An acquisition of Molycorp would echo a similar move from earlier this year, when an affiliate of Toyota bought half a Canadian rare earth deposit.

Rare earth users have also been casting about for sources of rare earths outside of China. As I noted yesterday, Japan thinks it might have landed a gold mine, so to speak, in Jamaica.

Also as I said yesterday, there’s another country that holds great promise as a future source. It’s a country that you might say is the opposite of Jamaica.
