The Congo Tantalum Rush

Logic Bomb writes: "The New York Times Magazine takes a look at the mining of a muddy substance called coltan. Once refined, it becomes tantalum, the crucial ingredient in capacitors. To put it simply, the modern high-tech world depends on this stuff. And while most of us have images of squeaky-clean chip factories and such -- in marked contrast to sleazy textile sweatshops -- it turns out that this industry has a dark side that takes a major toll on human lives. Definitely worth a read."

    Computer production has never been clean. In fact, it's nearly as dirty as the military.
    Now there's a loaded statement. Nowadays, the military is on the cutting edge of environmentally friendly technology. I'll admit, they had a lousy track record many years ago, but it's changed significantly.

    They've undertaken huge clean-up projects at most of their bases, plan every exercise & project for minimal environmental impact, and try to stay in strict compliance with US and state or host-nation environmental laws. Unlike many corporations that would rather pay the fines for non-compliance when it's cheaper.

    I speak from personal experience, in Air Force Civil Engineering. The construction projects I was involved in used high efficiency HVAC systems, low energy lighting, motion sensors that automatically turn lights off when rooms aren't in use, super-insulated buildings, toilets that use less water volume per flush, etc. These things all cost more up front, but have lower long-range operating costs. Now that I'm working in the private sector, commercial & residential clients forgo these systems for more traditional, environmentally unfriendly systems.

    Energy conservation wasn't even spoken about in the media in recent years, until Califonia's self inflicted energy crisis. The military has been heavily promoting it internally for several years.

    There was even a /. article a few months ago, about new bullets the Army is researching, for the sole reason they aren't harmful to our health & the environment like lead bullets.

    I think that's great if the military is using environmentally friendly techniques these days. But, you can't mask the military's long, sad history of fucking places up. At Hunter's Point in San Francisco, the Navy used to sail decomissioned ships to sea, nuke them, tow them back to port, sandblast all the radioactive gunk off, then dump it all in the bay. Oh, nice! There are also many hundreds of barrels of radioactive crap from Hunter's Point barried in 50-gallon drums off the Farallon Islands, one of California's unique marine habitats and probably its best diving spot. If you grab a chart of the San Francisco Bay, there are many areas that are marked off-limits because of underwater live ammunition dumps.

    The kicker about Hunter's Point is that the city is really having to lean on the Navy hard to get them to clean the place up. They only this year quietly admitted the existence of the radioactive goop. Before, we thought it was just PCBs!

  4. Not the "crucial ingredient in capacitors" by mr_data_esq · · Score: 5, Informative

    Hate to say it, but technically speaking, the article and the post are both way off. Tantalum isn't "the crucial ingredient in capacitors", and the electronics industry doesn't "depend on this stuff" at all. Most caps are made with ceramic materials (e.g. clays) or paper soaked in an electrolytic solution, but there are many other dielectrics available, like polypropylene, mica, etc., each with their own favourable characteristics.

    The nice thing about tantalums is that they are very small for the amount of capacitance they have - hence their popularity in PDAs and celphones. But they're expensive, and polarised - you have to plug them in the right way, or they literally blow up. They also can't tolerate much overvoltage.

    For the things that tantalums are most often used for (power-supply filtering), a kind of capacitor called multilayer ceramic actually works better. These are made mostly from nickel powder, and they're much cheaper and tougher. They're also non-polarised, which can reduce assembly costs, and they don't depend on hard-to-get tantalum powder.

    Last year there was a shortage of tantalum powder, which made tantalum caps really hard to get. Now word is getting out that the new breed of multilayer ceramic chip caps can do just as well, people aren't using tantalums nearly as much as they were. I think this is the real reason for the tantalum ore crash.

Today, the valley is home to more EPA Superfund sites (29) than any other county in the nation, with the most notorious of those sites -- from a leaking tank at a Fairchild Semiconductor fabrication plant -- poisoning a well that served the south San Jose neighborhood of Los Paseos. A subsequent study by the state's Department of Health Services found 2.5 to three times the expected rate of miscarriages and birth defects among pregnant women exposed to the contaminated drinking water, leading to a lawsuit and multimillion-dollar settlement in 1986 with over 250 claimants...."

    Well first of all, if you have the flu, the measles and the chicken pox all at once, you don't say "Hey, who cares if I catch pneumonia!" Just because you have lots of problems doesn't mean that it;s okay to have more.


    If anything, the establishment of mining and factories will add stability to the region, since the companies want to protect their money and investment.

    Secondly, did you actually read the article? There are no companies. There are no factories. And those mines are holes in the ground dug by people (roughly organized into "camps"). It's still anarchy, not good financial planning.

    Besides, you only get to mine your natural resources once, then they're gone. The article says that the money from coltan mining is not going into infrastructure like schools and roads. So what happens when the coltan is gone? Evenyone's actually worse off than they started, because there's no more money to be made by mining, and you've gained nothing that can increase the country's wealth in the long run (like schools!) in return.

    Correct me if I'm wrong, but hasn't the Congo been mined for diamonds for 100+ years now? Has it done any good? Why do you think the coltan situation will be different?

    If you had bother reading the article, you would know that innocent farmers are being murdered so rebel gangs can gain access to their tantalum rich land.

    These rebel gangs then sell the product to American and European corporations.

    Sounds like a major toll to me. But you're right, none of those farmers are starving now. Enjoy your electronic devices.
