What about metals? Gold comes to mind, but I thought there were a LOT of minerals in sea water.
The products we sell come from salt mines in NY. There are many salt deposits around the Great Lakes. American Rock Salt, Morton are the big ones south of Rochester, NY. There is even a mine directly under downtown Detroit. The bagged Calcium Chloride is made by Occidental Chemical or comes from China.
There’s about fifty pounds of gold in every cubic mile of sea water....
