"We specialize in small orders" Uranium Extract
from bulk Carnotite/Gummite Uranium Ore

The Uranium contained in bulk Carnotite and associated Uranium ores can be easily extracted to form various Uranium compounds. Typical Carnotite/Gummite Uranium ore. Use a hammer or rock crusher to smash the rock into a granular form. Wear proper safety equipment (gloves, dust mask, eye protection) when breaking the rock so you don't get rock fragments in your eye, or inhale piles of ore dust. Sift the crushed rock through a screen (a window screen or a spaghetti strainer will do). This will separate the large chunks from the fine, granular material. Weigh out 300 grams of the fine granular ore. Pour the 300 grams of fine ore into the barrel of your Ball Mill. A hard milling media is required, such as steel balls which are used here. Place the barrel on the mill and let it run for approximately 2 hours. This will reduce the ore into a very fine dust. This is necessary so the extraction chemicals will be able to react with the ore material. If Ball Milling is not done, very little Uranium will be extracted. After 2 hours of milling, the ore is as fine as Talcum powder. Separate the steel balls from the powdered ore by using either a magnet to pull out the balls, or dumping the barrel contents through a strainer. Certain types of Uranium ore (Pitchblende, Uraninite) can be simply extracted with Nitric Acid. However, Carnotite and its associated matrix minerals are far too alkaline for Acid extraction and many of the minor Uranium ores will not dissolve in acid. Alkaline extraction is called for when dealing with Carnotite ore. To begin, you'll need 200 grams of powdered Uranium ore, 50 grams of Sodium Carbonate, 25 grams of Sodium Bicarbonate (use Arm & Hammer Baking Soda) and 1000 ml of water. Place a large flask with the 1000 ml of water in it on a magnetic stirrer/hot plate, drop in a spinbar and heat to about 70-80ьз╕ C. Set the stir speed to maximum and slowly add each ingredient into the water while it is being stirred & heated. Let the mixture heat & stir overnight.  The next day, turn off the hot plate/stirrer and set the flask aside to cool and settle for 1 hour. After an hour, the heavy sediment will sink to the bottom leaving the cloudy extracted Uranium in a carbonate solution floating on top.   Pour the cloudy Uranium solution through a fine filter being careful not to let the bottom sediment to stir up or get into the filter.  The finished product will be a bright, clear yellow liquid: Uranyl Tricarbonate. In our next experiment, we'll use Kerosene and thttp://www.unitednuclear.com/extract.htmhe Solvent Extraction method to remove the carbonate from the Uranium.

How to Launder Stolen Bitcoins

Bitcoin’s main problem is that every transaction is public. Such a feature makes it difficult to launder stolen bitcoins. Take this $5m thief as the example. The person controlling 19,000 of Bitstamp’s coins has a problem. Anyone can follow the coins as they move between addresses. Lucky for them (or not as we’ll see), there exist tools to assist in hiding, disguising, and making it difficult to prove where your bitcoins originate.
Mixers combine your coins with the coins of others. Everyone sends coins to a central address. The mixer sends a transaction back to each user from the key controlling the central address. When stolen coins mix with ‘clean’ coins, they become difficult to track.
Coin Tumblers swap coins between users.  A Tumbler will mix coins, send transactions with various amounts to keys it controls; attempting to simulate other network transactions.  Sending a tumbler 1BTC may result in you receiving multiple, smaller, transactions in return over a short time. The bitcoins returned to you will have been combined, split and transacted many, many times. Taint is the probability of tracing coins back to any given address after mixing and tumbling.

A Google search will turn up half a dozen of these coin washing services. Many are a combination of the preceding concepts. The majority offer themselves to consumers as anonymizers protecting privacy. Whether they are tools for crime or a defense against tyrants remains in the hand of the user. As Cody Wilson, co-founder of the anonymous Bitcoin wallet ‘Dark Wallet’, has said “Liberty is a dangerous thing.”

Regardless of their deployment, these methods are not without weaknesses. Further, still, there are other ways to launder stolen bitcoins that may not require any extra services at all. Bitcoin mixes coins in transactions all the time. You’ve probably already done it dozens of times and never noticed.

How Tumblers Launder Stolen Bitcoins

A Bitcoin Transaction contains inputs and outputs. Inputs reference previous payments made to you. Outputs spend the coins by transferring ownership to a new address. A tumbler can launder stolen bitcoins by mixing and distributing them to other people and back to you.
Alice has previously received three payments.
1 BTC she bought on Coinbase,
2 BTC from her online store, and
3 BTC for selling weaponized wormhole technology to North Korea.
Alice controls 6 BTC with the keys in her wallet. If Alice sent all 6BTC in one transaction it’s not only reasonable, it’s likely, that someone analyzing the block chain will assume the same individual controls those keys. The transaction would join the Coinbase BTC and North Korea BTC in the same transaction with her online store proceeds as the inputs. Worse, still, if they are a government organization or Coinbase, they will be able to trace back the 1 BTC from Coinbase included in Alice’s transaction. Effectively, Alice is no longer anonymous, and her last transaction ties her to arms dealing with North Korea. Poor Alice.
Even if Alice were not laundering stolen bitcoins (or her North Korean coins), sending her coins through a tumbling service as she received them, she could have a higher chance of maintaining her anonymity.

The expertly made graphic demonstrates. Multiple users send their coins to the tumbler. The coins will be mixed, then split to many addresses, mixed to small groups, mixed to large groups, sent out again, etc. Over time, Alice will receive a number of payments totaling close to her original amount (minus the tumbler fees). Then, Alice could check blockchain.info’s taint analysis for her addresses and see the chances of being connected to her pre-tumbled coins.

Coin Mixing to Launder Stolen Bitcoins

If you’re planning to steal from an exchange and planning to launder stolen bitcoins through mixing here is how that works. In the section on tumbling stolen coins, Alice could potentially dox herself anytime she mixes coins she purchased from an exchange with other coins she controls.
Bitcoin Core developer Gregory Maxwell first described a new style of transaction, CoinJoin, that uses the same principle that connected Alice’s bitcoin keys. It was not developed to launder stolen bitcoins but protect privacy. The concept takes things many steps further. Transaction inputs are completely independent of each other. If a transaction contains one input from Alice and one input from Bob, they both must sign the transaction for it to be valid. Instead of a transaction containing only Alice’s inputs and outputs, a CoinJoin transaction contains inputs and outputs from many groups of people.
A group using CoinJoin agrees on a transaction ahead of time. Until everyone in the group signs the transaction, it is invalid. Including multiple people in a transaction makes it much more difficult to link other keys together based on the transaction alone. If Alice includes Bob in a CoinJoin transaction, it becomes more difficult to chip away at the walls of anonymity.

More Ways to Launder Stolen Bitcoins

These two principles to launder stolen bitcoins rely on the fact that bitcoins do not exist. The balance of bitcoins anyone controls are just numbers recorded in the block chain. When combined with a transaction, it is akin to adding “2 + 2″ and breaking apart the resulting “4” into “1;1;1;1″ There is no way of proving “Each ‘1’ is an equal quarter of each ‘2’ added to get ‘4’” or any other denomination.
The current Alpha release of Dark Wallet supports Stealth Addresses, in addition to CoinJoin and Multisig. A Stealth Address is another privacy-related feature in the works for Bitcoin. They don’t launder funds, so much as break the usual chain of custody the block chain provides for tracking bitcoins. Also, exchanges that implement hot/cold wallets can function as tumblers and mixers if users deposit and withdrawal from the same hot wallet
It’s important to end with the weaknesses. Both of these systems relies on a foundation of “legitimate” users to effectively launder stolen bitcoins. If the hacker, who stole BitStamp’s coins, were to offload all 18,000 bitcoins on the same tumbler or mixer at the same time, their volume would overwhelm the obfuscation they hope to attain. Similarly, including 18,000 stolen bitcoins in a CoinJoin with 100 other bitcoins would just give everyone highly tainted coins. It would take some time and effort to launder so many.

sodium pentothal = truth serum

The famed chemical sodium pentothal, which is commonly known as truth serum, has been a mainstay of spy flicks for decades. In real life, scientists have tested it on spies, psychiatric patients, pregnant women, and suspected criminals. They all talked, but did they say something meaningful? Or was it just what the people around them wanted to hear?

Like heroin, sodium pentothal is a brand name. The drug was manufactured and trademarked by Abbott Laboratories, and its free-for-all name is sodium thiopental. It's a barbiturate, a drug that acts on the central nervous system, which it depresses to calm anxiety, induce drowsiness, eliminate pain, and sometimes entirely knock someone out. That is not why it's become world famous. Sodium pentothal made its name in detective, spy, and pulp novels, where it was famously used as a 'truth sérum
