Iron ore should contain about 30 percent iron if it is to be mined profitably. Gold ores containing as little as 0.044 ounce (1.25 grams) of gold per ton can be mined at a profit. Magnesium can be removed from sea water at a profit by special methods. Gold, though present in sea water, cannot yet be extracted profitably.
