Mud-slinging over rare earth

When a row erupted between Japan and China last year over disputed islands in the East China Sea, an unexpected consequence was a big jump in the price of rare earth elements.

Q&A: Rare earth metals Rising tensions between China and Japan over an embargo may spell good news for miners looking to fund projects outside of China.

So what are rare earth metals?Well there are 17 of them. They are" Lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium.

What are they used for? Here is a snap shot: rechargeable batteries for electric and hybrid cars, advanced ceramics, electric car motors, computers, DVD players, and wind turbines. And there is more. Rare earths can be found in televisions, lighting, lasers, fiber optics, glass polishing, superconductors, and military hardware.

Is there an iPhone and iPad connection here? Naturally. Rare earths make for smaller, lighter batteries and motors. The drive to miniaturization was first used by the Sony Walkman personal cassette tape player. Rare earths are now key to making handheld gadgets such as Apple's iPhone and Research In Motion's BlackBerry.

Will demand continue to grow? Again, yes. The demand is set to grow by a minimum of 8 per cent a year. Electric vehicle demand is set to grow by an average of 790 per cent in the next five years.

The global supply of these commodities, required for a host of high-tech products including hybrid cars and smartphones, is largely controlled by China, while Japan is one of the world's leading consumers.

China is able to manage the global market because it is responsible for 97 per cent of the world's supply of rare earth elements, which are substances that can be extremely difficult and dangerous to mine. They consist of 17 metals in various forms.

Beijing's decision to halt exports of these elements to Japan after a dispute over Tokyo's arrest of a Chinese fisherman, whose vessel had collided with two Japanese coastguard boats, was accompanied by price rises that saw the cost of some rare earth elements increase sixfold.

The rise in prices has also been blamed on tighter export quotas imposed by China in the second half of last year, leading to concerns in Germany, the US and other countries, as well as Japan.

The situation is likely to remain serious, with reports indicating China has cut its export quotas for this year by as much as 35 per cent, citing its need to protect the environment, although observers believe the government's wish to protect domestic manufacturers is also a factor.

Only this week Taipei officials held talks with Beijing to try to ensure Taiwan can count on the supplies its industry needs.

Despite the apparent stranglehold China has on supply, countries that use rare earth elements in the largest quantities do have cause for optimism, as there are several factors that mean Beijing's grip on the market will, in time, lessen.

Michael Komesaroff, who has decades of experience in the industry and is now the principal of Urandaline Investments in Australia, says "China's dominance is not geologically predetermined".

Speaking on a visit this week to Beijing, Mr Komesaroff says there are "plenty of rare earths around in the world", and with prices having increased heavily, projects to mine them that were once deemed uneconomic will now be worth pursuing. That means in future the supply base is likely to become more diverse and in years to come, the proportion of known rare earth deposits held by China will decrease.

Also, as prices have risen so dramatically, manufacturers are finding ways to be more careful about how they use rare earth elements, a phenomenon known as "thrifting".

Just as aluminium cans became thinner as the price of the metal soared, so companies will learn to make better use of what rare earths are available.

Another strategy is finding alternatives and the Japanese, for example, are looking at developing synthetic rare earths, although Mr Komesaroff concedes "they've got a way to go".

So, with greater supplies in other parts of the world, and with manufacturers employing imaginative ways to get around or reduce their requirements for rare earth elements, China will in a few years time no longer be able to call the shots.

Conflict, drought, famine

Estimates of the number of deaths caused by the famine range from 400,000 to 1 million, according to a document prepared for the UK House of Lords in 2024.
It has been claimed that the policies of the Ethiopian government, which took control after deposing Emperor Haile Selassie in a military-led revolution in 1974, contributed to the scale of the famine.
Dr Miriam Bradley, senior lecturer in humanitarian studies at the University of Manchester, has argued that, by the early 1980s, “several government policies combined to cause, rather than prevent, a famine which lasted from 1983 to 1985. Mengistu’s government imposed Stalinist-model agricultural policies involving forced collectivisation and villagisation [relocation of communities into planned villages].
The West became aware of the catastrophe through a series of BBC News reports by journalist Michael Buerk in October 1984 describing a “biblical famine” and containing graphic images of thousands of people, including children, facing starvation.

Band Aid

Bob Geldof, singer with the Irish rock group The Boomtown Rats, formed Band Aid in response to the horrific images shown in the news broadcasts.
With Midge Ure of the band Ultravox, he wrote the hit charity single Do They Know it’s Christmas in December 1984, featuring a string of high-profile musicians.
Following the single’s success, the idea to stage a rock concert evolved.
Live Aid was a series of simultaneous concerts that took place at Wembley Stadium in London, John F Kennedy Stadium in Philadelphia, the US, and at various other venues across the world.
The combined event was broadcast to an estimated worldwide audience of 1.5 billion.

Tips to stay safe during hot weather

Stay hydrated: Drink plenty of fluids, especially water. Avoid alcohol and caffeine, which can increase dehydration.
Seek cool environments: Use air conditioning, fans, or visit community spaces with climate control.
Limit outdoor activities: Avoid strenuous activity during peak heat. If outside, seek shade and wear a wide-brimmed hat.
Dress appropriately: Wear lightweight, loose and light-coloured clothing to facilitate heat loss.
Check on vulnerable people: Regularly check in on elderly neighbours, young children and those with health conditions.
Home adaptations: Use blinds or curtains to block sunlight, avoid using ovens or stoves, and ventilate living spaces during cooler hours.
Recognise heat illness: Learn the signs of heat exhaustion and heat stroke (dizziness, confusion, rapid pulse, nausea), and seek medical attention if symptoms occur.
