When I stratified the powder some of the impurity were removed, however I'm not a chemist, so I have no clue what the purity of the uranium oxide was.

I found some one with a decent fume hood, and we decided to run the experiment to see what happens. I started with 800 grams of uranium marbles which should be, in theory, be 2% - 5% uranium oxide by weight. They were ground up into powder, than mixed into a solution of 20% hydrochloric acid. The mix was agitated for 3 hours before the solids were filtered out. The resulting liquid was brownish yellow in color. Inside of the fume hood we set up 2 hot plates, one at a higher elevation than the other. In the top flask was placed demineralized water, in the bottom flask the mixture. The top hot plate was set to 98C - the bottom one set to 110C. We ran a tube from the top to the bottom, and set up a drip that would be equivalent of the evaporation rate of the mixture. The mixture was left alone until the PH read 6.4 . The rest of the demineralized water was than emptied into the mixture, and it was left to boil off. Once there was very little of the liquid left, it was removed from the heat, and let to evaporate at room temperature. Once everything was evaporated off, I collected a brown/yellow powder and placed it on a "shaker table" normally used to separate gold partials from sand. After that was ran for a while, the impurities were scrapped off the top. Total yield was 9 grams of impure uranium oxide.

If I used Hydrofloric Acid, I'd end up with uranium hexafluoride gas + the impurity from all the glass

I would assume uranate - however it is imposable to tell just by looking at the glass. In any case, after reading some more, I would need to boil the HCL at 110C while diluting with distilled water until the hydrogen chloride is evaporated (( and extracted before it recombines with moisture in the air )). After an unknown amount of time, I could than evaporate the solution to receive the final product, which hopefully would be Uranium Oxide and not Uranyl Chloride .

I am not asking about dissolving glass - I am asking about extracting uranium oxide from uranyl chloride. The glass I just grind up into powder, than wash it in HCL to dissolve the uranium oxide. Edit: I may have the answer. If I heat the Uranyl Chloride just past 100C, The Chloride should vaporize, leaving behind uranium oxide. I'll have to look at this a bit more, however, as this is a very toxic method.

I know it this is not very efficient ( I can buy uraninite legally ) , however I would like to attempt to extract uranium oxide from glass by dissolving it in hydrochloric acid. I believe I will end up with uranyl chloride salts ( which are photosensitive ). I am not a chemist, however, and I am stuck on how to extract the uranium oxide out of the uranyl chloride . Any ideas ?
