At the biggest mining operation in the Bone Valley, Mosaic's Four Corners Mine, nine draglines work to strip away overburden and dredge up a matrix of sand, clay and phosphate pebble. The matrix is shot through a series of pipes about 10 to 20 miles long into a washer where the phosphate is screened and pumped into a slurry.

A century later, Florida's phosphate miners are highly trained technicians who sit in air-conditioned, 8-million-pound excavators. They unearth some 10 million tons of phosphate rock a year, supplying nearly a quarter of global demand for the "white gold" that helps crops grow.. Florida is home to one of the richest phosphate deposits in the world.
