In the past 30 years, the US has gone from the world's top phosphate consumer to the third largest, and now exports more phosphorus than it consumes (World Bank, 2012). Most of the new phosphorus use has been in India and China, which, together, now account for over 45% of the world's total consumption .

Here, In Alachua county, Florida, the people still have one last chance to turn down a phosphate mining proposal for the East side of Gainesville-It is important for our outer and inner bodies in this county that this proposal to mine, called Envision Alachua, is stopped.
Historically, Tennessee's most important mining products have been iron, bituminous coal, copper, lead, zinc, and phosphate. Iron ore was the most significant during early settlement years. Interest in the iron ore of the Western Highland Rim dates back to the 1790s and even earlier in the eastern mountains.
Phosphate rock production and consumption. U.S. production of phosphate rock in 2012 was 30.1 million metric tons, valued at $3.08 billion. Total world production of phosphate rock in 2012 was 233 million metric tons. China was the leading producer, with 41 percent of world production, followed by the United States, Morocco and Western Sahara.
"The International Strategic Minerals Inventory Summary Report – Phosphate" (USGS Circular 930-C) is a cooperative effort of this international group and was published in 1984 by the U.S. Geological Survey. It describes Phosphorus as "an important component of the cell tissues of plants and animals; it is necessary for the structure ...
In organic chemistry, phosphate or orthophosphate is an organophosphate, an ester of orthophosphoric acid of the form PO 4 RR′R″ where one or more hydrogen atoms are replaced by organic groups. An example is trimethyl phosphate, (CH 3) 3 PO 4.The term also refers to the trivalent functional group OP(O-) 3 in such esters.. Orthophosphates are especially important among the various ...
In 2000, nine companies operated seventeen phosphate rock mines in the U.S. Florida is the main source of phosphate rock in the U.S. It supplies 25 percent of the world and 75 percent of the U.S. demand for phosphate.2 Other large producing states are North Carolina, Utah, and Idaho.
Phosphate Deposits and Mining. Sedimentary phosphorites of marine origin are the most important phosphate deposits, but guano phosphate rock and even contemporary guano (modern bat droppings) are currently mined. Sedimentary phosphate deposits occur near shore, shallow marine environments along the continental shelf.

And phosphate mining in Florida, which is home to the world's largest phosphate mine, is being challenged by environmentalists concerned about its impact on waterways and drinking water supplies. Already, like other key commodities with once-dominant sources running low, the price of phosphate is starting to yo-yo alarmingly. Prices spiked at ...
ShareTweetSharePin0 SharesSince the turn of the twentieth century, the phosphate industry purchased large tracts of land in west central Florida, including the upper Peace River watershed. Florida's phosphate industry is mining in the Peace River basin, which also include "sovereignty lands". Florida's state agencies charged with "permitting" the phosphate industry to strip …
