Other Mineral Resources
Offshore areas of the US may contain resources of sulfur, salt, sand and gravel, phosphate rock, manganese nodules, and heavy-mineral placer deposits. To date, none of these has been produced for commercial purposes except sulfur and salt, although the MMS has allowed sand dredging in federal waters to restore damaged beaches in Maryland, Virginia, South Carolina, and Florida.
From 1960 to 2000, sulfur was mined by the Frasch process from the caprock of a salt dome at the Main Pass 299 mine, offshore Louisiana. A total of 34 million short tons of sulfur were recovered before the mine was closed; salt was also recovered.

Famous quotes containing the word resources:
“Everywhere we are told that our human resources are all to be used, that our civilization itself means the uses of everything it has—the inventions, the histories, every scrap of fact. But there is one kind of knowledge—infinitely precious, time- resistant more than monuments, here to be passed between the generations in any way it may be: never to be used. And that is poetry.”
—Muriel Rukeyser (1913–1980)
