Show I UTAH CABNOTITE. Result of Experiments Hade Upon Samples From Richardson. Before the American Philosophical society soci-ety recently, A. II. Phillips gave a de-Fcrlptlori de-Fcrlptlori of experiments made by him with oro from Richardson, in this State, containing about 10 per cent carnotlte. Discussing the results Mr. Phillips, In his discourse, said, nmnii? other things, that the radio activity of the product obtained was deemed sufficiently high to Indicate that radium could bo produced In quantity quan-tity from carnotlte, at least from this locality, lo-cality, as 25 pounds of rather lean oro had been used. Had u ton been worked over in the same way It would ha'e yielded a gram of chlorides of CO.OOO radio activity as compared to uranium This specimen as separated In November, 1902, and is as activo now as then. Carnotlte Is comparatively a new mineral, min-eral, having been described by Frledel and Cumengo In July., 1S39, nnd for this reason It is not found In most books on mineralogy, and Is therefore but little known to the general prospector. It was first discovered In tho western part of Colorado and occurs In Montrose, San Miguel and Mesa counties of that Stato and the adjacent counties of Utah. It Is a uranyl-potasslum vanadate with three molecules of water of crystallization. Carnotlte occurs as a light canary-colored powder disseminated through a lino grain sandstone. It is easily solublo in acids Jmd Is treated In this way' for tho com-fiflerclal com-fiflerclal production of uranium suits. |
