Rare Earth Elements: Extracting from Nuclear Waste?

In summary, there is no shortage of rare Earth elements themselves, but extracting them from nuclear waste would require a lot of effort and money. It is an economic and military issue because China has a lot of the rare Earth's and they can undercut the market.

How are rare Earth elements and minerals extracted from nuclear waste?
And I know that some people are saying that there is a low supply of rare Earth elements needed in high tech manufacturing, could that shortage be solved by extracting these rare elements from nuclear waste?

There's no shortage of the elements themselves, IIRC. We have plenty of them in the US. The trouble is that we stopped mining them and restarting that sort of mining operation on a large scale requires that a great deal of inertia be overcome. The Chinese never stopped mining them, so they have a fully operational system in place that would be hard to catch up with.

Extraction of rare Earth elements could be done chemically in wet process or pyrochemically (in a nonaqueous system).

However, one detriment to that plan is that some of the isotopes are still radioactive.

The availability of RE elements is largely an economic issue than a technical issue. China has a huge supply and they can undercut the market.

Its an economic and a military issue. A poor man sells whatever he can part with whenever he can, while the rich man maintains stockpiles for emergencies and sells whenever the price goes up. The US is wealthy so it often only encourages selling specific resources when the price goes up. For example, seafood farming is now a 70 billion dollar industry in the US. The government saw the world supplies diminishing and at the appropriate time encouraged growth in aquaculture. Some rare Earth's are more rare then others and demand for them is projected to increase dramatically in the coming decades.

Let's put your question in perspective. The world production of rare Earth elements is about 70,000 tons/year. The total world inventory of high-level wast eis about 65,000 tons. So even if 10% of it is rare Earth's (which I doubt) and you reprocessed all of it, you would only generate about one months supply. Does this sound worth it to you?
 

1. What are rare earth elements (REEs) and why are they important?

Rare earth elements are a group of 17 chemical elements that are essential for the development of modern technologies such as smartphones, electric cars, and renewable energy sources. They have unique properties that make them crucial for these applications, and there are currently no substitutes for them.

2. How are rare earth elements extracted from nuclear waste?

Rare earth elements can be extracted from nuclear waste using a process called solvent extraction. This involves mixing the waste with an organic solvent that selectively binds to the REEs. The mixture is then passed through several stages to separate the REEs from other elements.

3. Is extracting rare earth elements from nuclear waste environmentally friendly?

Yes, extracting rare earth elements from nuclear waste can be considered environmentally friendly. It reduces the amount of waste and toxic materials that would otherwise be disposed of, and it also reduces the need for mining and processing of rare earth elements from non-renewable sources.

4. Are there any challenges or limitations to extracting rare earth elements from nuclear waste?

One of the main challenges in extracting rare earth elements from nuclear waste is the low concentration of these elements in the waste. This means that a large amount of waste needs to be processed to obtain a significant amount of REEs. Additionally, the process can be expensive and technologically complex.

5. Can rare earth elements extracted from nuclear waste be used for commercial purposes?

Yes, rare earth elements extracted from nuclear waste can be used for commercial purposes. They have the same properties and applications as REEs extracted from other sources, making them valuable for various industries. However, further purification may be required to meet specific industry standards.
