Is this true or false? I am confused. Tests have been conducted to mine uranium from seawater.
My book says that at one time or another Japan, Germany, and the United States have expressed interest in the extraction of uranium. Japan set up a land-based test plant in 1986 to produce 10kg (26 lb) of uranium from seawater each year, but the operation has proved to be too expensive. So is the answer false?
I don't know that Japan set up a land based plant. To my knowledge, the Japanese have researched with sea based suspended absorbants to recover Uranium.
