“...every element on the periodic table is dissolved, in some measure, in sea water”
There was a guy on “Shark Tank” who wanted get gold out of seawater. He didn’t get a deal.
Gold extracted from sea water is by no means a new scheme, in any way. This “plan” has been around, in some form or another, since shortly after the Civil War, and always fails for the same reason - not economically feasible to extract what gold is there. We are talking about parts per BILLION, only about 1-2 milligrams of gold per ton of sea water.
