Page 9 - At present uranium oxide is sold in rather small quantities at $3 a pound, and in very small amounts at $5 a pound. Somewhat larger quantities are reported to be sold under contract at $2 a pound, or a little less ; and it is rumored that rather substantial sales could be effected at a price of $1.50. Carnotite contains the valuable element vanadium which is not present in the Congo ore. Credit for the sale of vanadium recovered from caruotite may be an important factor in the cost of extracting...
Page 51 - The CHAIRMAN. Governor, do you prefer to make your statement without interruption, and then respond to such questions as the members of the committee may desire to ask ? Governor BROUGHTON. Yes; but it will not bother me at all if anybody wishes to interrupt.
Page 5 - The uranium or radium content has not been given, but statements by persons having some knowledge of the ore, though not connected with the company, are that the ore shipped carries from 40 to 70 per cent U3O8, but the ore mined is undoubtedly in part much leaner.
Page 5 - ... mined is undoubtedly in part much leaner. As each per cent means about 2.57 milligrams of radium per ton of ore, it is easily seen that the total in the mined ore is very large. The treatment plant at Oolen, Belgium, began work in 1922, and 2.7 grams of radium (Ra) were turned out in December. * * * The total sales to the end of 1924 are said to have been 35 grams. The costs are not given, but are said to be only a few dollars per milligram. '• This competition, as is well known, caused the...

Mr. Kelly has charge of the question of when we have a sufficiency of information to justify bringing it to executive consideration of the bill. I will talk to him further about that. I want to say that the committee is very grateful to you gentlemen who have come from the Bureau of Mines and made such a splendid contribution of information touching the subject of radium and...
Page 9 - UaOs are sold on the basis of the uranium content which, as stated above, is proportional to the radium content. Only in exceptional cases have ores been elevated on the basis of both the radium and vanadium contents, but actually the presence of vanadium in American ores constitutes an advantage which should not be overlooked. When made into...

I began the use of radium in 1902 when the only radium available in the United States was a specimen brought over by the Smithsonian Institute for scientific research, before any medical work had been done in this country with radium. In 1906, I was awarded a silver medal at the Jamestown Exposition, for the demonstration of the application of radium to medicine. The CHAIRMAN. You may proceed to give us an account of its use to the present time, mentioning...
Page 32 - ... all do. But now the next thing to consider is what else we may do to promote this cause. Do we desire to hear from the Bureau of Mines on the question of costs and advisability, et cetera ? Mr. KELLY. Did you call the bureau. The CHAIRMAN. I did not, because I presumed we would cover all of this hour and that it would be a waste of time for them to be here. I think we are proceeding quite logically in getting now for the record Doctor ABBE. Finding out first of all whether or not there is a need...
