Japan Begins Recycling Rare Earth Metals From Electronics
Black Gold Alchemist writes "Dowa, a Japanese mining company in Kosaka, has begun the recycling of rare earth metals from used cellphones and computers. This is in response to a recent, temporary trade embargo from China, which is the leading supplier of rare earth metals needed for production of products including hybrid cars, wind turbines, and LCD screens. Because of the shortage of rare earth metals, Japanese trade minister Akihiro Ohata is asking the government to include a rare earth strategy in its supplementary budget for this year."
should have been doing this ages ago, but yet again, no pressure to do so while supplies were cheap

Well, this goes to show how much of electronics recycling is a gimmick and publicity stunt.
Separating rare earths out of electronics waste is actually not that difficult: hit it with acid; do some basic purification first to get rid of Fe, Cu and a few other "usual suspects"; after that ion exchange chromatography does the deed. Even without initial mechanical separation there should be enough of them in the acid effluent. The fact that it was not done shows how much are we really "recycling" there.
In fact, we should say thank you to China on this one. This may finally make EU, USA and Japan governments put some money behind the electronic waste disposal laws.

The technology has been around for years. I guess what is new is that the suits no longer see it as a "green" thing but as a necessary supply line.
10 ?"Hello World" life was simple then
like, for example, importing the stuff from mongolia. this may turn out to be the faster and cheaper way out.

The most interesting part of this mini-debacle is how did the idea that there would be a shortage of rare earth elements came about at all, and why did the Chinese believe it, the idea being utter bullshit.
While it is true that China manages to produce these cheaply at the moment, rare earth elements are available basically all over the place in similar proportions.
Using them as a policy-making tool has done no harm to Japan, and potentially a lot of harm to the credibility of China as an economic player, especially to its counterparties in Asia, but also anyone who may have a reason to expect potential future clash of interests.
While the Japanese acted out during the crisis as scared pussies, the Chinese appear to have played the role of the dumber party.
Seeing great Asian powers like Japan and China just learning to dab at foreign relations after 6 decades of American dominance is very interesting.
What this suggests is that there should be a middle ground between dumping stuff in a landfill and recycling it. We should be segregating material that we don't currently recycle or doesn't make economic sense to recycle, but might become scarce in the future. That will make it easier to recycle when we need it.
I have three old hard drives. When can Japan pick them up?
Sadly this is the way we overcome our big problems. Not by foresight, predictions and educated action. The shit has to start hitting the fan to get people moving in the right direction. I mean this whole rare earth situation has been foreseen. It was obvious that China was building a monopoly years ago. The same thing happens with the coming helium shortage, energy problems, global warming, you name it. It really has to get nasty for people to do something about these things.
In fact, we should say thank you to China on this one.
Recent news reports have Japan accusing China of this being over a territorial dispute. The traders are saying that things have resumed but that this is just an excuse for China to harass traders and outbound exports with "preshipment" checks. China denies this has anything to do with the dispute but the timing is more than a bit suspect and why is this only directed at Japan?
I don't know how much of an net positive environmental impact recycling rare earths from circuitry provides (is your acid economically and environmentally friendly? what are the byproducts? are they less damaging than the circuitry to the environment?) but I don't think it's wise to thank countries for exacerbating a territorial dispute. The world has enough of those now, we don't need another escalation or spat between countries.
My work here is dung.
Rare earths aren't really that rare. The noble gases actually live up to their family name to a much greater extent.
Set your phasers on "funky"!
Why do we act like dumps are black holes? It may not be economical at the moment. But, I don't see any reason we can't mine garbage dumps for minerals in the future. Hence I don't see why we need to get self righteous about moving minerals from one hole in the ground to another while using it as a cell phone in between.
China's move to this position would put DeBeers to shame. While I'm no fan of swadeshi, this certainly shows what happens in co-dependent relationships between nations.
that they have actually been doing recycling for a while (like copper, gold, silver etc) from motherboards.

You've all heard the "fly ash is nuclear waste too" bullshit from the 1970s from the Oak Ridge newsletter article that also suggested that terrorists could build nuclear bombs from coal ash. Stepping a little closer to reality there are other impurities in larger amounts. At coal fire power stations you can see whopping great big dams filled with water and light ash from the scrubbers. Most of the stuff in there is silica but heavier compounds sink and there should be some layering from gravity separation to concentrate things nicely.
There's bound to be some rare earths in there and it should be as easy to mine as sand. This was suggested to me by an engineer involved with the pollution control at a power plant in about 1994.
There is also the ash that comes out of the bottom but it would be more difficult to process and not concentrated (clinker etc).
great.. you know how well that worked with the housing market-- right?
A buttload of debt, and this system work so long as the borrowing continues-
it'll keep working right? we just increase the value of our home(country) and
refinance and buy a motorcycle or boat?
what is that you say? real estate crash? when did that happen?
what is this term? underwater? what does that mean?
how does it feel to know that the US is propped up by it's debt structure.
that if we were fiscally responsible, well- we'd be propped up by ya know, value.
not the threat of 'taking everyone down with us'

Seeing great Asian powers like Japan and China just learning to dab at foreign relations after 6 decades of American dominance is very interesting.
These countries have been doing foreign relations with each other long before U.S. was ever around, and before many European nations were around too!
Near Earth Asteroids and Space Junk have lots of Rare Earths...not far out when it becomes strategic...
While this sounds like a good idea, the problem is that segregating and storing all this stuff would be tremendously expensive (the cost of segregating recyclable materials is one of the main reasons why recycling programs have had somewhat of a checkered history). And there's no guarantee that it would ever pay off. So it would be tough to get anyone to invest in something like this.
so they are finally going to start building them gundams and have their turn to claim the territories of Asia (again) ?
Let's see how they will do with rare Mars metals :)
As with everything else, reuse is most always better than recycling.
Royalty-free standards should be created for battery shapes and connectors, and a garbage tax should be placed on non-standard batteries.
Interchangeable parts were key to the industrial revolution. Sometimes we forget.
I think it's that Japanese have always been meticulous in everything they do. They're also very good about following rules. In many countries, particularly the US, even people who believe in recycling would likely be pissed a the prospect of having to sort their garbage so extensively.
And I can't help but wonder, why is the recycling company not doing this? Aren't these people paying taxes so that their garbage is processed properly?
We in the US have a cultural problem where people get pissed off at anything that involves them moving a finger outside of their 9-5 work schedule.
I hear ya. What you are describing is one of the many symptoms of a malady affecting the US. There is this parochial, not-in-my-backyard backward mentality where the government/something/somebody must solve all their problems so long as it does not involve them physically or financially (.ie. taxes.)
Minimal government that can solve everything, including turning lead to goal. Anything else is labeled un-American. Any attempt to change is labeled unchristian socialism (even though they are hardly christian.) Despite the fact that they want it to solve all the job-related and financial problems to the point of implementing the most entrenched of market protectionist schemes (the very definition of a socialist state which is what they blindly deride.) Everything that they do not understand (or involves them to move a bit out of their fatass comfort zones) is labeled as the very thing they actually would end up having if they had their way.
Unlike the previous generations, nowadays, this country is at its position of financial and industrial primacy not because of its people, but despite of them. Asking them the most innocuous of things, like recycling, is a bit too much an affront of their personal freedom, a most un-American thing.
Basically, it is insane that the west (esp. America) buys goods from China, and then pays china to take them back. Instead, it is better for us to do some R&D and build up cheaper automated recycling to get various things back
I prefer the "u" in honour as it seems to be missing these days.
I saw a grad project at the Colorado School of Mines that basically ground up circuit boards into sand which ends up having a much higher ore content than what we're pulling out of mines. Ramping it up to industrial proportions will take a little while but if the economics change (and it always does), ramp up occurs sooner.
