Separating Rare Earth Elements (Byte-sized Science)

[@johnrehwinkel7241]

Pretty general, an explanation of why they're chemically similar (due to the electron orbitals and valance electrons) would be useful, as well as why they're economically important (like gadolinium for MRI contrast or europium as a phosphor activator).

This is what i have been dreaming my whole life and just now you opened my eyes more. this is a life changing discovery ! God bless you all.

Keep up advancing and innovating.

Indian mining industry is operating in an unscientific manner as a result we are loosing huge amounts of rare Earth Materials We have failed to identify mine and process these rare Earth Materials; Cement, Infra and construction industry uses the majority of mineral reserves without knowing that it may be loaded with some of the most expensive elements

[@oportillo02]

It is because many of local legislation doesn't allow to mine metallic elements, usually give permission to extract rocks for construction purposes.

What are the different costs of extracting REEs during their various processes stages?

[@lanaeb27]

Do you have a process to separate Scandium, Thulium, Strontium, if so how? These minerals are in a fine sand mixture. wondering if magnets would be a good option?

[@davidrussell8795]

I can't answer how to separate the rees,but a magnet can remove iron in small quantities, but the next thing to use is what my freinds had in the roofing biz to pick up lost nails around the job,it's known as a " roofers magnetic bar" it a magnetic bar about the size of a shop broom.Some come with wheels and a handle! Just place it under something like a sheet of plastic and let the sand slide over it! Thus will remove some,with a lot of manual.labour! There is a magnetic converor belt system that I saw a scrap yard use to remove brass turnings from steel,works great! Anyways,if you remove 90% of the iron before selling it or sending it in for processing, you will benefit from this with lower costs in the separation plant! And higher returns!

looking into separating rare earths from used electronics ( cellphones and laptops ) i can get the materials to very fine grind just need input on recovery methods any advice?

[@SimplyScienceNRCan]

Thank you Mike B for your question! Our research is focussed on rare earth elements/minerals recovery from primary sources (mineral ores) and not from secondary or post consumer resources such as computers and mobile phones. Unfortunately, we do not have any advice to offer you.

Can 65 ree elements be bubbled apart from sand?

[@umeyamish4598]

hey sir can you please guide me how to separate lanthanum (La) from bastnaesite . i know we can separate REEs from it by flotation process( as you explain it ) but when it come to separate La from REEs is quite challenging . please guide me or make a video for solvent extraction technique and also mention the chemical we can use for it .

[@kisho2679]

could rare earths be created artificially (instead of geological extraction)?

[@hagel4742]

If we could create material with the same properties yes it might be possible

Where can I get a sample tested for rare earth minerals

[@davidrussell8795]

Just look up an " Assay lab" in your area. There are several in Vancouver. I used ALS ,there's also ACME Labs in Vancouver. Others as well. Als charges about 270 for a rock and sand sample, and they tried to charge me administration fees on 2 samples but I got them down ti one admin fee for both. My au assay cost about 70$, but for some reason they did not do it at the same time! This gets expensive with lots of samples! Also ask them what type of assay they'll perform! With rees, mine said they could not aqua digest some rees! So I'm short on a few ree minerals assay. I did a sand sample with the rock,it cost another 65$ so both cost me about 270 with one admin fee. I had to send them back more sand for an AU assay which they did separately,and a peice of rock,they didn't do an au assay on as well! Hope that helps! David @ARC EXPLORATION INC

[@pariskennard4540]

Thank you!!

[@davidrussell8795]

@pariskennard4540 Are you just getting my message today! Oh BTW,my au tested @ .005 ppm! So according to my calculations that would take around 240 tons of sand to produce "1" ounce of au! So that would definitely be a byproduct of separation!

Can you separate samarium??? And if yes how?

[@SimplyScienceNRCan]

Hi, thank you for your question! The answer is a bit complex because this depends on what samarium is being separated from. Samarium can be separated from other elements in leach solutions. Its separation from other rare earth elements is quite complicated, but that’s how it’s produced. The techniques used for rare earth elements separations are generally varied and complex, depending on the composition of the solution and the number of element(s) targeted for separation. For instance, high-purity individual rare earths, including samarium, can be separated using several techniques. Let’s suppose that we want to separate samarium from europium. One such technique is a combination of photochemical reduction and extraction chromatography. First, europium is reduced. Then, extraction resin is used to separate the two. Whereas samarium is captured by the resin, europium remains free and is separated by washing. Then, samarium that has been absorbed on extraction resin is separated by elution. The other technique used to separate samarium from europium is solvent extraction using ionic liquid. Samarium can be separated from gadolinium similarly using solvent extraction. Clear as mud, right? Hope this helps!

[@whitenight82]

@@SimplyScienceNRCan Fun insight into the processes thank you. I spent many years making simple rare earth compounds in very small to large batches. I always thought it would be a pain to get them into pure oxide for industrial use.

[@mrkickback2010]

This scientist needs to travel to China and help them with their rare earth mineral processing. China rivers are becoming highly toxic and threatens to pollute the yellow river.
