I'm too lazy I'm afraid - but let me tell you there was a US company which proposed doing exactly that, extracting gold from seawater, it was a scam of course but you can't stop free enterprise. What they should have done was list on the ASx, pay their fees, and they would have been home free.....
it's only a matter of time before someone tries it again....
(just for the record - the latest estimate of gold concentration in sea water is one gram in one hundred million tons of sea water - jeeze.... that's a higher concentration than BLR's uranium...... LOL)
