showed a very amall
percentage of uranium = residual uranium per
gram of copper and thie compares very favorably with the vre-Atomis Energy produced
copper semple,.
Next slide, please.
We found thet the contaminated
aluminum showed the highest-amount of cone
tamination of any of the nenples that we
analyzed, 4980 micrograms of U per gram,
The remelt showed considerable
surface contamination as evidenced by both
the drillings and also by the Juno meacurements,
The slag contained anproximately
half the contemination shown in the original
slag and thia is probably due to the fact of
aluzinun’s affinity for oxygen, having an
affinity greater than any other metal ore
including ureniun,
And therefore the uranium was not allowed to oxidize and could not
come off in the slag.
