The current spot price for U_3O_8 is $98 per kilo in New York. How do you get your cost of $120 per kilo? Is it from a reference? Did you do the calculation your self? If so, can you please share the details. 3ppb is a lot of water and salt to sift through.
It was from research put out by The President's Committee Of Advisors On Science And Technology in 1999. The report was wanting the USA to get into the international effort to get uranium out of sea water. Also it should of been 120 US dollars per lb not tonn. I just pulled up my research and saw I made a mistake
I was going off two year old research I did for an op-ed piece. Looking back into it Japanese researchers have developed a new system that is basically a large braid of specially treated fabric that is anchored to the sea bed like sea weed. Or it is placed in floating cages. It absorbs not only uranium but other useful heavy metals. Cost according to the paper is 96 US dollars per lb.
I couldn't find the paper I got my 120 dollar lb number, the URL is no longer valid, most likely archived in the White houses archive. However I do have the report from the Japanese researchers. http://physics.harvard.edu/~wilson/energypmp/2009_Tamada.pdf" [Broken]
