DailyDirt: Valuable Metals Abound
from the urls-we-dig-up dept
Things that we use every day, like cell phones, computers, and other consumer electronics, actually contain a wide variety of valuable metals, such as europium, dysprosium, neodymium, terbium, and yttrium. When these electronics reach the end of their useful life, these metals are often lost to landfills if they're not properly recycled. Rather than let these useful materials go to waste, the U.S. Department of Energy is now working to recover rare earth elements from used consumer products, using methods employed in nuclear fuel reprocessing. Here are some other examples of ways to get at valuable metals.- Researchers at Murdoch University have developed a faster and cheaper microfluidics approach to recover precious metals like platinum and palladium from spent automotive catalyst. The new technique could also be used for the purification of rare earth elements. [url]
- British company Metalysis is hoping to isolate useful metals like tantalum, titanium, neodymium, tungsten, and vanadium from their oxides via electrolysis in molten salt at 1,000 degrees Celsius. The electrolysis is done directly on the powdered oxide, which acts as the cathode and is gradually transformed from the oxide to the metal. [url]
- Companies like Planetary Resources and Deep Space Industries have ambitious plans to mine asteroids for useful metals (and water). Planetary Resources plans to build a couple of low-cost robotic prospecting spacecraft that can survey, intercept, and process asteroids, and then deliver the resources directly to where they're needed. DSI has similar plans, but it's also developing a 3D printer ("Microgravity Foundry") that will be able to create high-quality metal components in orbit. [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

we'll be mining our garbage soon...

Every home consume materials shouldn't that waste be transformed at the home level somehow, turn every house into a mini refinery for raw materials.
I think about cells each and everyone of them do something and their waste is collected and disposed and then it gets reused by other organims.
Beer is something that most people would understand in this manner.
Yeast multiply and consume sugar and poops alcohol, that then is reuse by us to produce other things, and when we poop we create an environment for other bacteria to live in.
So we are reaching a point were turning houses into production cells make sense.
If any country is a human body, that body is missing a liver.

Re: Re:
also there is a great deal of gold found in sewage treatment plants, seem a high percentage of people lose their gold fillings by swallowing them. Also diamonds are commonly found in raw sewage. (for some reason). But lots of got. (and corn !!!,, chew your corn) :)

but the extraction of the metals and elements from electronics is a very dangerous and toxic process. (as is gold mining generally) (but more so).

"Murdoch University."
"How were your grades?"
"All A's. I guess you could say I was a member of an elite team."
"Now the world you must face, man."
"I hope someone can hire me."
