#Silmet
Silmet vs vereraha.
Pathetic.

🇪🇪 At Estonia’s request, the EU removed a Russian rare-earth metals supplier to Estonian firm Silmet from its new sanctions list, RFE/RL editor Rikard Jozwiak reports.

This comes after Usmanov and Fridman. Oh, #Estonia 🥲

The Silmet plant in Estonia was once a major source of rare earths to the US. It is still producing them and just developed a process for heavy rare earths. They've also had a process for minimizing waste.

Seems like nobody has heard about them, though.

Mul ei ole Äripäeva tellimust aga väidetavalt on alternatiivid olemas ja tuvastatud, kuid mitte paremad kui Venemaa?
Silmet otsib juba kümme aastat väljapääsu Vene toormest. “Alternatiiv on olemas, aga see ei pruugi meile meeldida”

I'm happy to hear this! Back when they were Molycorp, they owned the Silmet rare-earth refining plant in Estonia, where I helped develop that no-waste refining process. I hoped they would bring it to Mountain Pass!
The unique thing about this mine is not just that it is producing ~15% of the world’s RE oxide BUT MP Materials is also refining them onsite in an extremely clean way with NO harmful byproducts or pollution.

I wish I could share photos but you could eat off the floor there!

Sõda käib viiendat aastat ja siiani pole alternatiive leitud? Venemaal pole muldmetallide monopoli, kindlasti saab neid Hiinast.

Muldmetallid pole tegelikult väga haruldased, aga nende töötlemise võimekus pole väga laialdane. Silmet on selle koha pealt meile väärtuslik vara.
I didn't know Estonia 🇪🇪 had so strong cards in tariff negotiations. What are the odds Trump knows where Estonia is? Kinda think the existence of it might be a suprise to him

BTW, for the ignoramuses now tearing up the government, developing that process for Silmet was funded by the US government. We engaged a mining engineering firm in Denver, so the money stayed in the US.

And we got a process that works better for critical minerals!

Win-win!

Sõda kestab VIIENDAT aastat ja Silmet pole tegelenud teise tarnija leidmisega?

Reminder to new users here:

The Silmet plant in Sillamäe, Estonia, refined uranium ore into yellowcake until the mid-1980s, when it was converted to rare earth products.

Its kilometer-long tailings pond was remediated in 2009, and the port there competes with Russia's Ust-Luga.
Reminder to new users here:

Among the insect parasitic nematodes, infective juveniles in the genus Heterorhabditis mature to hermaphroditic adults, while those in Steinernema mature as male or female individually.
Reminder to new users here:

Early Canon FD lenses are identifiable by their metal barrels and silver breech lock rings; later New FD or nFD lenses are all black without the breech lock rings and were built with more plastic, making them less solid but much lighter.

I'm pretty sure I have a process diagram of the Silmet process. The Mountain Pass refinery probably has changed it a bit.

ACTUALLY...

I happen to have worked with a rare-earth refining plant, Silmet, in Estonia. There is capacity there, and capacity coming in Mountain Pass, California, based on the Silmet plant.

And the process is not smelting.

I don't know why this doesn't get more press.

Estonsko požádalo o vyřazení ruské firmy z 22. balíčku sankcí. Informovala o tom portál ERR Kerstin Lepik, tajemnice zastoupení této pobaltské republiky v Bruselu. Jedná se o společnost NPM Silmet

Have you seen the process at the Silmet plant in Estonia?

I see you're researching critical minerals. If you ever are interested in the Silmet plant, producing rare earths in Estonia, I can probably help. I helped them with the cleanup of their tailings pond.

I love this photo. That big green area used to be the tailings pond.

A mine and mill are being developed at Mountain Pass, California. The company owning them has experience with the Silmet plant in Estonia, where I worked with the management to introduce a low-waste refining process. I hope they are taking what we learned to the mill in California.
